Merge tag 'exynos-drm-next-for-v5.17' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-next

Four cleanups
- Replacing lagacy gpio interface of dsi driver with gpiod one.
- Implementing a generic GEM object mmap and use it instead of
  exynos specific one.
- Dropping the use of label from dsi driver. Which also fixes
  a build warning.
- Just trivial cleanup by dropping unnecessay code.
