mainboard/google/poppy: Enable separate MRC cache for recovery mode
Enable separate MRC cache for recovery mode. This requires change in
flash layout to accomodate another region for RECOVERY_MRC_CACHE.
BUG=b:37682566
TEST=Verified following scenarios:
1. Boot into recovery does not destroy normal mode MRC cache.
2. Once recovery MRC cache is populated, all future boots in recovery
mode re-use data from the cache.
3. Forcing recovery mode to retrain memory causes normal mode to retrain
memory as well.
