Is this child node really necessary? There will never be more then
one connector per CC line.

We should prefer device_graph* functions over of_graph* and
acpi_graph* functions in the drivers so we don't have to handle the
same thing multiple times with separate APIs. Is it still possible if
there is that connector child node?
