ACPI4.0/5.0 have clear description: 

FIRMWARE_CTRL: If the X_FIRMWARE_CTRL field contains a non zero value then this field must be zero.
X_FIRMWARE_CTRL: This field is used when the physical address of the FACS is above 4GB. If the FIRMWARE_CTRL field contains a non zero value then this field must be zero.

Update code in AcpiSupport/AcpiTable when it produces this field to set one only.
Update code in AcpiS3Save when it consumes this field, check 0 value.
