intel/rangeley: Update UPD_DATA_REGION to support POST-GOLD 2 FSP
Rangeley POST-GOLD 2 FSP added PCIe ports de-emphasis configuration by UPD input. Update UPD_DATA_REGION structure for matching up this FSP change.
PcdCustomerRevision is a debugging aid that will be output to debug message in FSP. When needed, it can be customized by BCT tool for tracking BCT configurations.
