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

   Sorry for late. This pull request includes some enhancements
   for Exynos drm, new feature supports, cleanups and fixups
   like below,

   - Consider low power transmission for drm mipi dsi module,
     and also add non-continuous clock mode support for Exynos
     mipi dsi driver.
   - Add Exynos3250 SoC support.
   - Enhance and clean up ipp framework and fimc driver.
   - Update to use component match support and fix up
     de-initialization order.
   - Remove a direct mmap interface and relevant stuff specific to
     Exynos drm, use drm generic mmap interface instead.
     And we will remove the specific interface from userspace
     library, libdrm soon.
   - Use universal plane which allows to replace fake primary plane
     with the real one.
   - Some code cleanups and fixups.
