[PATCH 2/2] drm/i915/xehp: Annotate a couple more workaround registers as MCR

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.
