Merge branch 'exynos-drm-next' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-next

Browse source 
Summary:
- Clean up HDMI and MIXER parts
- Clean up legacy structures specific to Exynos DRM
  . This patch series removes existing exyons_drm_display and
    exynos_drm_encoder structures specific to Exynos DRM, and
    makes them to replace with common drm_encoder structure.
    With cleanup patch, we removes exynos_drm_encoder module.
- Clean up gem, dmabuf and buffer modules
  . This patch series replaces existing Exynos DRM dmabuf codes
    with common drm prime ones, and embeds all codes of exynos_drm_buf
    into exynos_drm_gem module.
    With cleanup patch, we removes exynos_drm_buf and exynos_drm_dmabuf
    modules.
- And some fixups.
