Subject: drm/fsl: Drop drm_vblank_cleanup
Git-commit: ffe881fba1e8467872fcb926fe2817aedbec2592
Patch-mainline: v4.13-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

Again cleanup before irq disabling doesn't really stop the races,
so just drop it. Proper fix would be to put drm_atomic_helper_shutdown
before everything gets cleaned up.
