[PATCH v6 10/10] drm/vc4: hdmi: use drm_atomic_helper_connector_hdmi_hotplug_edid()

[Dmitry Baryshkov]

Use the helper function to update the connector's information. This
makes sure that HDMI-related events are handled in a generic way.
Currently it is limited to the HDMI state reporting to the sound system.
