drivers/intel/fsp2_0: Add support for recovery MRC hash space in TPM

This space is read/updated only in recovery mode.
1. During read phase, verify if the hash of MRC data read from
RECOVERY_MRC_CACHE matches the hash stored in TPM.
2. During update phase, calculate hash of training data returned by MRC
and save it in TPM.

BUG=chrome-os-partner:59355
BRANCH=None
TEST=Verified MRC data hash comparison and update operation on reef.
