Merge tag 'exynos-drm-next-for-v5.6' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-next

Change Exynos DRM specific callback function names
- it changes enable and disable callback functions names of
  struct exynos_drm_crtc_ops to atomic_enable and atomic_disable
  for consistency.
Modify "EXYNOS" prefix to "Exynos"
- "Exynos" name is a regular trademarked name promoted by its
  manufacturer, Samsung Electronics Co., Ltd.. This patch
  corrects the name.
