MLECO-2948: Minor refactoring for platform modules.
Reducing dependency on cmsis-device sources as these will
be removed under MLECO-2944. Also, starting to refactor
to allow HAL to drop NPU and TA init routines - this will
happen in future CRs.
Added platform driver for native, and subsequent patches
will attempt to get rid of the HAL "profile" specific
sources and allow platform stub implementations at a level
below HAL. This will allow platforms drivers to only
override the range of functions that they actually want to
implement and will fall back on stubs for the rest. In this
CR only "utils" have been removed.
