driver/intel/fsp2.0: Add External stage cache region helper
If ramstage caching outside CBMEM is enabled i.e CONFIG_CACHE_RELOCATED_RAMSTAGE_OUTSIDE_CBMEM, then a helper function to determine the caching region in SMM should be implemented. Add the same to FSP2.0 driver. FSP1.1 driver had the same implementation hence copied stage_cache.c. The SoC code should implement the smm_subregion to provide the base and size of the caching region within SMM. The fsp/memmap.h provides the prototype and we will reuse the same from FPS 1.1.
