security/tpm: Include mrc.bin in CRTM if present
mrc.bin, on platforms where it is present, is code executed on CPU, so it should be considered a part of CRTM. cbfs_locate_file_in_region() is hooked to measurement here too, since mrc.bin is loaded with it, and CBFS_TYPE_MRC (the type of mrc.bin) is measured to TPM_CRTM_PCR rather than TPM_RUNTIME_DATA_PCR. TODO: I have heard that SMM is too resource-limited to link with vboot library, so currently tspi_measure_cbfs_hook() is masked in SMM. Please correct me if I am wrong.
