Subject: drm/i915/gvt: Fix cmd parser error for Passmark9
Git-commit: 3e1f4c491559998615cc8ee287c673f0f7e66534
Patch-mainline: v5.18-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
This is to add one new register required for windows guest driver
update when running Passmark9, otherwise cmd parser would complain
and fail guest workload.
