Commit 358e76fd613a ("drm/sun4i: hdmi: Consolidate atomic_check and mode_valid") added a call to drm_atomic_get_new_connector_state() but didn't include drm_atomic.h which defines it. On some configuration, this leads to a build failure, presumably because in the common case the header gets included by an intermediate header but it isn't always the case. Let's add a proper include.
