[PATCH v3 04/11] drm/dp_mst: Register connectors via drm_connector_dynamic_register()

MST connectors should be initialized/registered by calling
drm_connector_dynamic_init()/drm_connector_dynamic_register(). The
previous patch adding these functions explains the issue with the
current drm_connector_init*()/drm_connector_register() interface for
MST connectors.

Based on the above adjust here the registration part and change the
initialization part in follow-up patches for each driver.

For now, drivers are allowed to keep using the drm_connector_init*()
functions, by drm_connector_dynamic_register() checking for this (see
drm_connector_add()). A patch later will change this to WARN in such
cases.
