Provide a helper to extract the devicetree node_id for a GPIO
controller from a gpio phandle array. This can be used with
DEVICE_DT_GET() to directly reference the corresponding controller
device.

We have a use case for checking the results of a DT_PROP_HAS_IDX()
call with COND_CODE_1(). That won't work because its expansion is an
integer comparison; COND_CODE_1() expects a literal 1 or 0.
Adjust the macro implementation so it expands to a literal 1 or 0.
Make this work even when the index argument needs an expansion while
we're at it.

Add the first API functions that directly deal with node dependency
ordinals as determined by edtlib:
- DT_DEP_ORD(node_id): node_id's ordinal
- DT_REQUIRES_DEP_ORDS(node_id): list of dep ordinals for node_id's
direct dependencies
- DT_SUPPORTS_DEP_ORDS(node_id): list of dep ordinals for nodes
depending directly on node_id
- DT_INST_ equivalents
This is not meant to be an exhaustive set of macros related to
dependency ordinals; rather, it's a starting out point meant to enable
initial struct device dependency tracking work. We can add more if
needed.

In case a "required: False" enum binding doesn't mention a
default value, but a default value makes sense to be set in the code,
DT_ENUM_IDX_OR could be used to provide the default idx to be used.
New macro comes with appropriate tests.

Now that device_api attribute is unmodified at runtime, as well as all
the other attributes, it is possible to switch all device driver
instance to be constant.
A coccinelle rule is used for this:

Add a variety of property and specifier cell accessors that fall back
on a default value supplied by the caller if the devicetree does not
contain the requested data.
This is useful for avoiding use of COND_CODE_1() and similarly tricky
macros in applications and drivers.

Move some common macros shared between different unit test functions
up to the top of the file to make them easier to spot and keep them a
bit tidier.
This cleanup excludes macros that are only used for specific purposes
in a single function.

This commit is a cleanup in two test samples.
In both samples, the following line of code were found:
set(DTS_ROOTS ${CMAKE_CURRENT_LIST_DIR})
Firstly, it is not needed to set `DTS_ROOT` in samples, as the sample
folder is always added to `DTS_ROOT`.
Secondly, the variable is named `DTS_ROOT`, but the samples used a
misspelled version `DTS_ROOTS`, which means that variable has never
had any effect.

This makes a difference when building with CMake and forgetting
ZEPHYR_BASE or not registering Zephyr in the CMake package registry.
In this particular case, REQUIRED turns this harmless looking log

Add the installation prefix of "Zephyr" to CMAKE_PREFIX_PATH or set

"Zephyr" provides a separate development package or SDK, be sure it
has been installed.
