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.
