Subject: drm: arcpgu: Fix module unload
Git-commit: 0c43ff59e71b37b1fc550e9fdd6399c77b8fee68
Patch-mainline: v4.14-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

At module unload we are expecting a struct drm_device but at
probing we are not setting it right. Fix this and correct the
arcpgu module unload.
