Merge tag 'exynos-drm-next-for-6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-next

Two cleanups
- Drop .owner from platform_driver declaration of each exynos drm module.
- Drop the cleanup code to device_node object in exynos_hdmi.c using
  the scope-based resource management feature[1].
