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.
