drm/imx: atomic phase 1: Use transitional atomic CRTC and plane helpers
Use the drm_plane_helper_update/disable() and drm_helper_crtc_mode_set()
transitional atomic helpers. The crtc->mode_set_nofb callback is added
so that the primary plane is no longer tied to the CRTC. Check/update
logics are separated to make sure crtc->mode_set_nofb and plane->atomic_update
are always successful. Also, some necessary logics are tweaked for a smooth
transition.
