Enable the USB3.0 host node, and gadget node. The gadget is available through the USB type C connector on the board. The connector is tied to a Fairchild fusb302b device, which currently does not have a driver in U-boot, but the node is here for correct description of the board + Linux future compatibility. It will be easier to move the node as-is when it will be available in the DT from Linux
