mrc_cache: Move mrc_cache_*_hash functions into mrc_cache driver
This CL would remove these calls from fsp 2.0. Platforms that select MRC_STASH_TO_CBMEM, updating the TPM NVRAM space is moved from romstage (when data stashed to CBMEM) to ramstage (when data is written back to SPI flash. BUG=b:150502246 BRANCH=None TEST=make sure memory training still works on nami Change-Id: I3088ca6927c7dbc65386c13e868afa0462086937 Signed-off-by: Shelley Chen <shchen@google.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/46510 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Furquan Shaikh <furquan@google.com> Reviewed-by: Julius Werner <jwerner@chromium.org>
