For atomic modeset, we need to set the sync signal polarities from the CRTC state structure rather than the legacy mode structure stored in CRTC. In any case, we should update this from our mode_set_nofb() method, rather than the commit() method. Move it there, and ensure that armada_drm_crtc_update() will not overwrite these bits.
