[PATCH] drm/sun4i: hdmi: Add missing drm_atomic header

[Maxime Ripard]

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.
