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
commit 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 commits 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 commit later will change this to WARN in such
cases.

v2: Replaces references to a "patch" with "commit" in the commit log.
