In PR #26836, we switch nSIM from custom legacy ARC UART model
to ns16550 model, which will allow us to use zephyr images build for
nSIM on other platforms like HAPS, QEMU, etc...
In PR #27334, which introduce new board nsim_em7d_v22, has gone
parallel to the switch to dwuart, and is still using legacy model.
With wrong configuration, the uart for nsim_em7d_v22 has no output,
which cause all tests failure.

Typically we have ARC core configurations where Fast IRQs (FIRQ) are
enabled together with multiple register files and those we have covered
by testing. But FIRQ & single register bank we only happen to have on
the older EMSK v2.2.it might be a good idea to add a similar
configuration to nSIM "boards" so that we keep it tested regularly.
nsim_em7d_v22 configuration is similar with em_staterkit_em7d_v22,
both configed with FIRQ & single register bank.

ARC_MPU_VER 2 has a strong requirement in
* size, must be >= 2048 bytes and power of 2
* start address must be aligned to size
It may bring a big waste of memory.
On the other hand, GEN_PRIV_STACK is used for ARC_MPU_VER 2,
it conflicts with MPU_STACK_GUARD.
So considering the limmitations, remove MPU_STACK_GUARD for
ARC_MPU_VER 2

Given that nsim_em can run the tests instead of just building them as
with em_starterkit_em7d, make it a default platform instead of
em_starterkit_em7d to get most of the testing when nsim simulator is
installed on the developer machine.
Tests run are 1000x more useful than just building them, even if we do
not have a large installed base of nsim.

Same deal as in commit eddd98f ("kconfig: Replace some single-symbol
'if's with 'depends on'"), for all symbols defined within defconfig
files. See that commit for an explanation.
Maybe 'if's were used originally to mirror the 'if's in the main Kconfig
files, and then it got copied around by people assuming 'if' must work
differently from 'depends on'. It doesn't match in every spot at least.
Better to keep it simple and just consistently use 'depends on' when
it's a single symbol/choice I think. Helps reinforce that 'if' isn't
magic too.
Verified by printing all Kconfig menu nodes (symbols, choices, menus,
etc.) before and after the change and diffing (should show no
difference).

All board defconfig files currently set the architecture in addition to
the board and the SoC, by setting e.g. CONFIG_ARM=y. This spams up
defconfig files.
CONFIG_<arch> symbols currently being set in configuration files also
means that they are configurable (can be changed in menuconfig and in
configuration files), even though changing the architecture won't work,
since other things get set from -DBOARD=<board>. Many boards also allow
changing the architecture symbols independently from the SoC symbols,
which doesn't make sense.
Get rid of all assignments to CONFIG_<arch> symbols and clean up the
relationships between symbols and the configuration interface, like
this:
1. Remove the choice with the CONFIG_<arch> symbols in arch/Kconfig and
turn the CONFIG_<arch> symbols into invisible
(promptless/nonconfigurable) symbols instead.
Getting rid of the choice allows the symbols to be 'select'ed (choice
symbols don't support 'select').
2. Select the right CONFIG_<arch> symbol from the SOC_SERIES_* symbols.
This makes sense since you know the architecture if you know the SoC.
Put the select on the SOC_* symbol instead for boards that don't have
a SOC_SERIES_*.
3. Remove all assignments to CONFIG_<arch> symbols. The assignments
would generate errors now, since the symbols are promptless.
The change was done by grepping for assignments to CONFIG_<arch>
symbols, finding the SOC_SERIES_* (or SOC_*) symbol being set in the
same defconfig file, and putting a 'select' on it instead.
See
https://github.com/ulfalizer/zephyr/commits/hide-arch-syms-unsquashed
for a split-up version of this commit, which will make it easier to see
how stuff was done. This needs to go in as one commit though.
This change is safer than it might seem re. outstanding PRs, because any
assignment to CONFIG_<arch> symbols generates an error now, making
outdated stuff easy to catch.

Fix the following device tree warnings:
unit-address and first reg (0x40000) don't match for iccm@0
unit-address and first reg (0x80040000) don't match for dccm@80000000
Re-work iccm and dccm reg address and size to be based on #defines.
This allows the nsim_sem_normal.dts to override defaults that are set in

generated_dts_board.h is pretty redundant and confusing as a name. Call
it devicetree.h instead.
dts.h would be another option, but DTS stands for "devicetree source"
and is the source code format, so it's a bit confusing too.
The replacement was done by grepping for 'generated_dts_board' and
'GENERATED_DTS_BOARD'.

Now when SMP support for ARC is available we may introduce a simulation
platform which might be used for testing & development for SMP setups.
One important note is stand-alone nSIM (as well as its "Free" flavour)
doesn't support SMP simulation so we have to switch to use of nSIM via
proprietary MetaWare debugger [1] and so:
1. We introduce new emulation target "mdb"
2. It's only possible to run that platform for those who
have MetaWare tools installed and valid license.
Though QEMU port for ARC is in work at the moment and once we
open that port and it has SMP support we'll switch to it and everybody
will be able to try ARC HS with SMP.

ARC nSIM simulates pretty much any modern ARC core,
moreover it emulates a lot of different core features so
it is possible to play with them even wo real hardware.
Thus we add yet another ARC core family to be used on simulated
nSIM board.
For now it's just a basic configuration with ARC UART for
smoke-testing of Zephyr on ARC HS CPUs.

This commit adds 'clock-frequency' property to the cpu nodes.
The clock frequency specified in the added property is used
during platform configuration. Examples:
- The SWO logger uses clock frequency to configure SWO output.
- Plenty of platforms need CPU clock specified for their HAL.
- Most of devices with USB needs information about CPU clock
in order to configure USB clock source.

ARC EM4 is just a baseline configuration of ARC EM family of CPU cores.
But with addition of more featuers like caches, DSP extensions etc
we're effectively getting EM6, EM5D etc templates.

as that's what makes sense together with extra features but not
templates itself.
