Clean up the code a bit:
- Simplify the loops over the flash 'reg' properties by using range()
- Build identifier names with a plain .format() where possible. This
makes them stand out better in the code.
- Remove redundant variables
- Move variables close to where they're used
- Misc. other minor improvements
generated_dts_board.conf and generated_dts_board_unfixed.h were verified
to be identical for disco_l475_iot1 and frdm_kw41z before and after the
cleanup.

DT_ALIAS_<ALIAS>_<PROP> defines are a convenient and portable way to get
the device instance name despite different naming conventions used by
the device drivers.
Signed-off-by: Piotr Mienkowski <piotr.mienkowski@gmail.com>
Its possible that the <INSTANCE> number could conflict with the register
number. This is shown to happen for a device like soc-nv-flash at
address 0.
So change naming convention to DT_INST_<INSTANCE>_<COMPAT>_<PROP> and
make DT_<COMPAT>_<INSTANCE>_<PROP> as deprecated.

Because of how generate defines for instances its possible that we have
a name conflict if the instance ID and reg addr space clash.
For example on qemu_x86 there are current two 'soc-nv-flash' nodes and
one is at reg addr 0, but instance id 1, the other is reg addr 0x1000
and instance id 0. We'd possibly get this conflict:
For the 'soc-nv-flash' at 0x1000 (instance 0):
(instance define)
#define DT_SOC_NV_FLASH_0_BASE_ADDRESS 0x1000
For the 'soc-nv-flash' at 0x0 (instance 1):
(address define)
#define DT_SOC_NV_FLASH_0_BASE_ADDRESS 0x0
To deal with this we make sure that the lower reg address is instance 0,
than things work out ok. To handle this case, if we sort the instance
IDs based on reg addr than if we have something at reg addr 0, it will
also than be an instand ID 0.
The longer term solution will be to deprecated the old defines and
remove the conflict between instance ID defines and normal DT defines.

We added generation of aliases for "alt-label" (which was the outer
label of a node) for use with shields and connectors. However we've
never used these defines and the generation is a bit inconsistent.
This removes generation of defines like for label 'arduino_spi':
#define ARDUINO_SPI_BASE_ADDRESS ... (already deprecated)
#define DT_ST_STM32_SPI_FIFO_ARDUINO_SPI_BASE_ADDRESS ...

If we have something like:
#address-cells = <1>;
#size-cells = <0>;
intc: ioapic@fec00000 {
compatible = "intel,ioapic";
reg = <0xfec00000 0x100000>;
};
We should generate:
DT_INTEL_IOAPIC_FEC00000_BASE_ADDRESS_0
DT_INTEL_IOAPIC_FEC00000_BASE_ADDRESS_1
Instead we generated:
DT_INTEL_IOAPIC_FEC00000_BASE_ADDRESS
DT_INTEL_IOAPIC_FEC00000_BASE_ADDRESS_1
This was due to logic deciding if '_0' should be used not taking into
account #address-cells & #size-cells correctly.

We generated some alias defines for children of a bus in which we had a
path alias for the bus node. We never used these defines, we don't
recommend they get used (child of busses should use instance defines)
and they were only generated in small handful of cases (for dts that had
path aliases to the bus node - i2c or spi).
Remove this as effectively dead code.

gpio-map is a property of "nexus node", defined in dts v0.3.
It allows to describe a pin connector so it can be referenced
through phandles and hence used in expansion device nodes like a
shield header (typically implemented through overlays).
This change implements gpio controller resolution through these maps.
Few assumptions were taken in order to simplify the implementation.
These assumptions bring some limitations to the use of gpio-map
but my understanding is that this should still allow to cover most
use cases.
Assumptions:
-gpio-size is the same for all gpio-controllers referenced in a map
-optional properties gpio-map-mask and gpio-map-pass-thru are
supposed to be omitted
The understanding of this last assumption is that flags provided in
the expansion device node will overwrite the connector flags.
In a latter stage, when need happen, these limitations can be
revisited to unlock fully fledged gpio-map usage.

The /memreserve/ code would crash if it ever ran, because 'name' isn't
defined (seems to be some copy-paste here). There are no /memreserve/s
in Zephyr though, so it works out.
'name' seems to be the node name. Not sure what to put for a

Discovered with pylint3.
Use the placeholder name '_' for unproblematic unused variables. It's
what I'm used to, and pylint knows not to flag it.
Also improve the naming a bit in devicetree.py. If a key/value is known
to be a specific thing (like a node), then it's helpful to call it that
instead of something generic like "value".

_extract_flash() or _extract_code_partition() depending on which
magic string was passed in. Call them directly instead.
- Fold constant and globally available parameter values into functions
- Remove DTFlash._flash_node. It's easy to derive wherever it's needed,

be called in any order).

- Add a global err() function for reporting errors. Use it if a node
unexpectedly has no interrupt-parent.

PyYAML 5.1 was just released and it doesn't support !include as
previous versions do. This breaks our DTS bindings parsing.
Let's fix our extract_dts_include.py script to work with both
3.13 and 5.1.
Also, update the pyyaml requirement to >=3.13 to be sure we're
compatible.

To reproduce the issue this addresses, run "cmake -B96b_nitrogen"
twice with Python 3.5. Observe the order of the flash partition table
changing in:
"build{1,2}/zephyr/include/generated/generated_dts_board.conf" and
"generated_dts_board_unfixed.h"
Dictionaries are iterated in a random order by Python 3.5 and before.
This could have caused "Unstable" CI in PR #13921 and maybe others.
Anyway we want builds to be determimistic by default. Explicit
randomness can be added for better coverage but not by default.

- No deep copying is needed. The deepcopy() is just a hack to work
around that the value might not be a list. That deserves a comment at
least.
- A catch-all try/except will hide stuff like misspelled variables as
well. It's usually a bad idea.
Rewrite things to be more explicit, and add some comments.
reg.py was indirectly using the deepcopy() imported in global.py,
because it does 'from global import *'. Have it import deepcopy() itself
instead. reg.py is the only remaining user of deepcopy().
reg.py relying on the deepcopy() import in global.py was super hard to

If a binding specifies 'generate: define' for 'interrupt-names' (like
some bindings do), then that ought to generate #defines for it, but the
scripts/dts code currently hardcodes 'interrupt-names' to be ignored
(along with some other properties).
Maybe the 'generate: define' in those bindings is a mistake, but the
code still ought to respect it. That also gets rid of some mystery code.

extract_property() is meant to generate #defines for a single property,
like 'foo = <1 2 3>'. Currently, it also generates node-level #defines
related to parent buses.
That makes the intent of the code hard to understand, and also means
that identical node-level #defines get redundantly added multiple times
(once per property).
Generate the node-level bus #defines before processing properties, in
generate_node_defines(). Use a new generate_bus_defines() helper.

After lots of reverse-engineering, I understand why deepcopy() is used:
1) Various functions defined in scripts/dts/extract/* modify the list
of names in-place
2) A plain list.copy() won't work when the *-names property happens to
have a single name in it, because devicetree.py gives a string
instead of a list in that case
Using deepcopy() to solve (2) is very confusing (especially with no
comments), because no deep copying is actually needed.
Get rid of deepcopy(), add a helper function for fetching the names, and
some comments.
