Those ports uses different instructions to get accessed: in/out
instructions. It differs in many ways with memory access, and it's much
slower. It's unset by default, but some arch exposing legacy UART ports
might need it.

Avoid adding platform data to defconfig directly and instead
use Kconfig. This will allow overrides.

This adds the config options to enable the driver for those GPIOs,

This reduces the defconfig file to only those options needed
for the platform. We also introduce a kernel independent config
file (no micro/nano prefix) that be the default.
Sanity checks depends on the nano/micro file naming, so until it
is modified to support the new model, we keep the old files.

Add support for a "generic" ARC implementation. This is a misnomer
since ARC platforms are synthesized by the SOC vendor and are specifc
to a given vendors implementation/configuration. This platform
support if for an SOC where we are allowed to let the code to support
the SOC into the wild but not allowed to name it in public.
This change allows to work on support for the SOC in the open and let
the rest of the community see the evolution of of the platform.
