Refactors all of the on-chip GPIO drivers to use a shared driver class
initialization priority configuration, CONFIG_GPIO_INIT_PRIORITY, to
allow configuring GPIO drivers separately from other devices. This is
similar to other driver classes like I2C and SPI.
Most drivers previously used CONFIG_KERNEL_INIT_PRIORITY_DEFAULT or
CONFIG_KERNEL_INIT_PRIORITY_DEVICE, therefore the default for this new
option is the lower of the two, which means earlier initialization.
Driver-specific options for off-chip I2C- or SPI-based GPIO drivers are
left intact because they often need to be initialized at a different
priority than on-chip GPIO drivers.

Currently there is no way to support running a board on multiple
emulation platforms nor to choose a desired emulation platform for the
simulation to be run on. This commit introduces a new
SUPPORTED_EMU_PLATFORMS list, which defines available emulation
platforms for a given board.

Currently the default runner of nsim_hs_smp is mdb,
the runner of other nsim platform is nsimdrv, user
can't change the default runner unless he uses
west command(--runner).
With this change cmake will choose runner according
to BOARD_DEBUG_RUNNER or BOARD_FLASH_RUNNER. so if
add -DBOARD_FLASH_RUNNER=mdb-nsim or
-DBOARD_DEBUG_RUNNER=mdb-nsim to cmake command,
the apllication will be run with mdb.

The idea of having default platforms is to prioritize running tests over
just building them. We do not have NSIM in CI and thus we are just
building for those platforms without running the tests, so, we spend
lots of time building on PRs which slows everything down. This is
already done in the daily builds.
We now have Qemu covering ARC. If we can get NSIM into CI, then we
should reconsider enabling some NSIM platforms.
Leaving hs_smp and _sem for coverage, we do not have other platforms
covering those.

The board has an I2C GPIO expander on it. A number of samples utilize
LEDs on GPIOs for testing purpose so it makes sense to enable the GPIO
expander (CONFIG_GPIO_CY8C95XX) driver when CONFIG_GPIO has been
enabled. We have to also enable I2C since the expander is connected
over an I2C interface.

As of today the build-only testing in upstream is enabled for
nsim_em and nsim_em7d_v22 which are very similar from the
compiler POW. The ARC HS, ARC Secure EM and SMP targets miss
any testing.
So adjust default testing for better coverage by enabling
build-only testing for nsim_hs, nsim_sem and nsim_hs_smp and drop
excessive testing for nsim_em7d_v22.

XIP (eXecute In Place) is a method of executing programs directly
from long term storage (i.e flash memory). It allows us to
avoid copying text it into RAM, saving writable memory for dynamic
data and not the static program code.
We don't have such non-volatile memory capable for executing in
place on HSDK so we load Zephyr image to DDR memory with debugger
each time.

Instrs_per_pass option specify the number of instructions excuted
before simulator switches operations. the default value is 512. If we
specify a small value for it the debugger's overhead will increase
significantly for simulation because of the time taken to rapidly
switch operations. And the overhead will cause some time critical
task failure.
Restore instrs_per_pass value from 10 to default 512, we will have a
good sanitycheck result for nsim_hs_smp.

mdb runner is quite special as it can be used to run Zephyr on

However it is really misleading as same command (west flash)
will run Zephyr in simulation for one board and try to run it
on HW for another board. Things are getting worse for boards
supporting both runs in simulation and on real hardware.
Let's split mdb runner for mdb-hw (for runs on HW) and mdb-nsim
(for runs in simulation) runners.
