mainboard/google/reef: clear normal MRC cache on recovery retrain

For Chrome OS the normal MRC cache should be cleared when a hardware
    retrain recovery request is observed. The reason is that since there
    are 2 different MRC cache slots there needs to be a mechanism which
    allows an end user make a system bootable again if the MRC settings
    happen to not allow the system to boot any longer. Therefore, one
    just needs to enter recovery with the hardware retrain flag and
    the system normal MRC cache slot will be invalidated.
