Subject: drm/exynos: mixer: simplify mixer_graph_buffer()
Git-commit: 1e60d62f3811e5c446738a85f61bed5d84de113b
Patch-mainline: v4.14-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

DRM core already checks in drm_atomic_plane_check() if the
pixelformat is valid. Hence we can collapse the default case
of the switch statement with the XRGB8888 case.

No functional change.
