soc/intel/common: remove mrc cache assumptions
Update the mrc cache implementation to use region_file. Instead
of relying on memory-mapped access and pointer arithmetic
use the region_devices and region_file to obtain the latest
data associated with the region. This removes the need for the
nvm wrapper as the region_devices can be used directly. Thus,
the library is more generic and can be extended to work on
different boot mediums.
