Subject: drm/i915: split general MMIO setup from per-GT uncore init
Git-commit: 498f02b657b7a591c61cf269f7b02dc136231ea1
Patch-mainline: v5.17-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225
In coming patches we'll be doing the actual tile initialization between
these two uncore init phases.
