This patch relpaces specific atomic commit function
with atomic helper commit one, which also includes
atomic_commit_tail callback for Exynos SoC becasue
crtc devices on Exynos SoC uses power domain device
so drm_atomic_helper_commit_planes should be called
after drm_atomic_helper_commit_modeset_enables.
