I am afraid I am unable to help you on this. I wasn't really pay attention when usb-connector was introduced and not sure how it can replace extcon. Now after read usb-connector.txt, it seems the binding only defines a/b/c-connector, but not ab-connector, and there is no enough information (at least for me) explaining how VBUS and ID fix into this usb-connector binding.
Maybe Rob can provide some hint.
