Subject: [PATCH] drm/vc4: hdmi: Call HDMI hotplug helper on disconnect
drm_atomic_helper_connector_hdmi_hotplug() must be called
regardless of the connection status, otherwise the HDMI audio
disconnect event won't be notified.
Fixes: 2ea9ec5d2c20 ("drm/vc4: hdmi: use drm_atomic_helper_connector_hdmi_hotplug()")
