Subject: drm/amd/display: Set all update flags when we have full update
Git-commit: 1402c605173bbbb1c2f7e615a1708a6ee61c69c3
Patch-mainline: v4.18-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166
To prevent future optimization related bugs, just set all update
flags when we have a full update, since we know we want to reprogram
everything in that case.
