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.

- add dts config and defconfig for different core configuration.
- end files with a newline in boards/arc/emsdp/board.dtsi
- remove unused head in boards/arc/emsdp/doc/index.rst
- ARC_MPU_VER in different core is fixed. so remove some useless code

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.

The ARC HS is a family of high performance CPUs from Synopsys
capable of running wide range of applications from heavy DPS
calculation to full-scale OS.
Still as with other ARC cores ARC HS might be tailored to
a particular application.
As opposed to EM cores ARC HS cores always have support of unaligned
data access and by default GCC generates such a data layout with
so we have to always enable unaligned data access in runtime otherwise
on attempt to access such data we'd see "Unaligned memory exception".
Note we had to explicitly mention CONFIG_CPU_ARCEM=y in
all current defconfigs as CPU_ARC{EM|HS} are now parts of a
choice so we cannot simply select ether option in board's Kconfig.
And while at it change "-mmpy-option" of ARC EM to "wlh1"
which is the same as previously used "6" but matches
Programmer's Reference Manual (PRM) and is more human-friendly.

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.

The ARC timer is a MHz-scale cycle counter and works very well with
the new 10 kHz default tick rate. Remove the settings for ARC
hardware.
Note that the nsim board definitions are left at 100 Hz. That is a
software emulation environment that (like qemu) exposes the host clock
as "real" time and thus is subject to clock jitter due to host
scheduling.

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.
So to not confuse users let's talk about families of ARC cores
as that's what makes sense together with extra features but not
templates itself.

Same deal as in commit 4638652214 ("Kconfig: Use 'default' instead of
'def_bool' in Kconfig.defconfig files"), fixing new stuff that got
introduced since then.
Some symbols, like ALTERA_AVALON_PIO, are only defined in
Kconfig.defconfig files, and so need the def_bool.
Motivation (from the note at the end of
guides/kconfig/index.html#common-shorthands):
For a symbol defined in multiple locations (e.g., in a Kconfig.defconfig
file in Zephyr), it is best to only give the symbol type for the "base"
definition of the symbol, and to use 'default' (instead of 'def_<type>'
value) for the remaining definitions. That way, if the base definition
of the symbol is removed, the symbol ends up without a type, which
generates a warning that points to the other definitions. That makes the
extra definitions easier to discover and remove.

Right now only numerical values are printed which must
be looked up in the Designware ARCv2 ISA Programmer's
Reference, which is not public.
Add a non-default Kconfig to print more information at
the expense of footprint, and enable it for all the simulator
targets.
We only print code/parameter details for machine check and
protection violations, more may be added later as desired.
This should cover all the exceptions we commonly encounter
for memory protection.
