Subject: drm/exynos/mixer: enable support for 1024x768 and 1280x1024 modes
Git-commit: 0900673e366190328796903a72cf17a9d082c327
Patch-mainline: v4.15-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

Since HDMI can handle these modes despite of MIXER limitations let's
enable them.
