[PATCH v3 06/11] drm/amd/dp_mst: Expose a connector to kernel users after it's properly initialized

[Imre Deak]

After a connector is added to the drm_mode_config::connector_list, it's
visible to any in-kernel users looking up connectors via the above list.
Make sure that the connector is properly initialized before such
look-ups, by initializing the connector with
drm_connector_dynamic_register() - which doesn't add the connector to
the list - and registering it with drm_connector_dynamic_register() -
which adds the connector to the list - after the initialization is
complete.
