soc/intel/common: Implement TBT firmware authentication validity check

After Thunderbolt firmware is downloaded to IMR, its authentication
validity needs to be checked. This change implements the valid_tbt_auth
function. Thunderbolt DSD and its corresponding IMR_VAID will be
present to kernel only if its authentication is successful.

BUG=b:188695995
TEST=Validated TGL TBT firmware authentication and its IMR_VALID
into SSDT which is properly present to kernel.
