Merge branch 'exynos-drm-fixes' of git://git./linux/kernel/git/daeinki/drm-exynos into drm-fixes

Summary:
- Use generic function to get buffer count instead of specific one.
  In case of Exynos DRM, There was a special case which decides pixel
  format of a given buffer according to planer types, which is NV12M and NV12.
  However, NV12M doesn't exist in drm fourcc so it removes
  exynos_drm_format_num_buffers() specific to Exynos DRM and use a generic function,
  drm_format_num_planes() instead.
- Allow mixer driver to support NV21 format for Video processor.
  This format was already supported but we just missed DRM_FORMAT_NV21 case
  so this patch considers the case so that Mixer driver can handle it correctly.
- Add regression fix and some code cleanups.
