The GW71xx, GW72xx and GW73xx boards have USB1 routed to a USB OTG connectors and USB2 routed to a USB hub.

The OTG connector has a over-currently protection with an active-low pin and the USB1 to HUB connection has no over-current protection (as the HUB itself implements this for its downstream ports).

Add proper dt nodes to specify the over-current pin polarity for USB1 and disable over-current protection for USB2.
