Subject: gpu: drm: gma500: remove dead code
Git-commit: 94d7fb4982d2145c5784e33fa973ffb9ebb086ac
Patch-mainline: v4.13-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

Local variable use_gct is assigned to a constant value and it is never
updated again. Remove this variable and the dead code it guards.
