commit 4c79865f3e8a2db93ec1e844509edfebe5a6ae56 upstream.

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.
