Subject: drm: rcar-du: Let core take care of normalizing the zpos
Git-commit: 75def7785f4901b65a89dc99ea9506b1395242fa
Patch-mainline: v4.18-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166
Set the drm_mode_config->normalize_zpos and call drm_atomic_helper_check()
from rcar_du_atomic_check() instead of re implementing the function locally.
