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.
