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.
