soc/intel/common: provide option to invalide MRC cache on recovery

Allow a board/platform to invalidate the normal MRC cache when
    hardware retraining is requested in recovery mode. A small 4 byte
    payload is used to update the latest data written. It will of course
    fail on MRC cache retreival on next usage.
