[ Upstream commit 7649a5d1f263b8cc5c2827ef0443ead9bee9ae0e ]
GAMSTLB_CTRL and GAMCNTRL_CTRL became multicast/replicated registers on Xe_HP. They should be defined accordingly and use MCR-aware operations.
These registers have only been used for some dg2/xehpsdv workarounds, so this fix is mostly just for consistency/future-proofing; even lacking the MCR annotation, workarounds will always be properly applied in a multicast manner on these platforms.
