Subject: drm/i915/pvc: Read correct RP_STATE_CAP register
Git-commit: 4de23dca7ec8dfb191ea80fbfe3f008d4ed52346
Patch-mainline: v6.0-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 jsc#PED-2849
The SoC registers, including RP_STATE_CAP, have moved to a new location
in GTTMMADR on Ponte Vecchio. We need to update the register offset
accordingly.
