Subject: [PATCH 07/30] drm/bridge/analogix/anx78xx: Add missing drm_dp_aux_unregister() call

Surprisingly, this bridge actually registers it's AUX adapter at the
correct time already. Nice job! However, it does forget to actually
unregister the AUX adapter, so let's add a bridge function to handle that.
