Lyude Paul 85ddbe2c4a drm/bridge/tc358767: Don't register DP AUX channel until bridge is attached
Since this is a bridge, we don't start out with a respective DRM device.
Likewise this means we don't have a connector, which also means that we
should be following drm_dp_aux_register()'s documentation advice and not
call drm_dp_aux_register() until we have a matching connector. Instead,
call drm_dp_aux_init() in tc_probe() and wait until tc_bridge_attach() to
register our AUX channel. We also add tc_bridge_detach() to handle
unregistering the AUX adapter once the bridge has been disconnected.
