drm: Add drm_connector_init() variant with ddc
Allow passing ddc adapter pointer to the init function. Even if
drm_connector_init() sometime in the future decides to e.g. memset() all
connector fields to zeros, the newly added function ensures that at its
completion the ddc member of connector is correctly set.
