From: Leo Li <sunpeng.li@xxxxxxx>
drm_atomic_helper_check_planes() calls the crtc atomic check helpers. In
an attempt to better align with the DRM framework, we can move the
entire dm_update dance to the crtc check helper (since it essentially
checks that we can align DC states to what DRM is requesting)
