Does the DWC3 block require Vbus to power itself? Doubtful. This
belongs in a usb-connector node. If the DWC3 driver wants to get the
Vbus supply, it can fetch it from that node.

Ah, now I understand. There's a vbus-supply in the connector in newer
kernel versions than the one I have to test with. It'll have to wait
until I've been able to upgrade the kernel version for this board.
