The ns16550 flags reg-shift property as optional. In case it is not
supplied, the ns16550 driver relies on a value defined in <soc.h>, or,
by default it takes 4 (shift by 2).
This patch adds the property to all ns16550 nodes, with the following
values:
- 2 if SoC did not have any custom value defined by
UART_REG_ADDR_INTERVAL (corresponds to 1 << 2 = 4)
- If SoC defined DEFAULT_REG_INTERVAL (snps_arc_iot/it8xxx2), use such
value (4=2, 2=1, 1=0).
These changes will allow simplifying the ns16550 driver.

Currently we use incorrect memory layout for SMP boards as
we put data (which need do be accessible from all cores) to
DCCM which is private for each CPU core.
This works for nSIM which doesn't simulate CCMs (as we don't pass
corresponding nSIM options for SMP configurations) however
it won't work if we run that code on real HW (we want to achieve
that nSIM configurations are also runnable on HAPS - FPGA platform).
Let's fix that issue by using DDR instead of CCMs for SMP
configurations (nsim_hs_smp and nsim_hs6x_smp).
While I'm at it - switch UP HS6x configuration (nsim_hs6x)
for DDR usage instead of CCMs - to make that configuration closer
to the HAPS config we have.

The simplest way of getting networking to work on really tiny embedded
system is to use an extra serial port as an interface to external world
with help of a SLIP,
see https://en.wikipedia.org/wiki/Serial_Line_Internet_Protocol.
The catch is on a deeply embedded system we most likely won't see
an Ethernet MAC in the system as it might be as large ans as complex
as the CPU itself so there's no point in adding it. Moreover it will
require support in drivers, which are very hardware specific
(not only IP-block specific, but also need to take care of all the quirks
made in this particular instance and platform).
But with SLIP we may use existing serial port of the board which already
has all the needed support and with a platform-agnotic code of SLIP
we may have usable networking on both simulators & real HW boards.
And that's what we do in Zephyr.
Now we teach ARC's QEMU platform to do so as well.

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.

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.

LEDs on GPIOs for testing purpose so it makes sense to enable the GPIO
expander (CONFIG_GPIO_CY8C95XX) driver when CONFIG_GPIO has been

over an I2C interface.
