Merge tag 'exynos-drm-next-for-v4.16' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-next

Remove lagacy IPP driver
- This driver isn't used anymore so remove it. Marek is preparing new one
  which includes completely rewritten API so this driver will be replaced
  with the new version[1] later.
And cleanups.

* tag 'exynos-drm-next-for-v4.16' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos:
  drm/exynos: ipp: Remove Exynos DRM IPP subsystem
  drm/exynos/decon: Add include guard to the Exynos7 header
  drm/exynos/decon: Move headers from global to local place
  drm/exynos: decon5433: Remove unnecessary platform_get_resource() error check
