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

Hardware / Coreboot - Furquan Shaikh [chromium.org] - 10 November 2016 11:10 UTC

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.
