abandon: merge this #7334 - intel/fsp_baytrail: add Gold3 FSP support
Intel Baytrail Gold2 and earlier FSP Staying Supported
UPD_DATA_REGION structure has been updated to support Baytrail Gold3 FSP, but incompatible with previous FSP. Adjust the offset of those changed fields if FSP version is early than Gold3.
