When trying to split up the initialisation phase and the registration phase, one immediate problem encountered is trying to use our own i2c devices before registration with userspace (to read EDID during device discovery). drm_dp_aux in particular only offers an interface for setting up the device *after* we have exposed the connector via sysfs. In order to break the chicken-and-egg problem, export drm_dp_aux_init() to minimally prepare the i2c device for internal use before drm_connector_register().
