In the patch ("arm64: Disable GiC priorities on Mediatek devices w/ firmware issues") we've moved the quirk handling to another place and so it's not needed in the GiC driver. NOTE: this isn't a full revert because it leaves some of the changes to the "quirks" structure around in case future code needs it.
