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.
Fixes: 6f30b27c5ef5 ("arm64: dts: imx8mm: Add Gateworks i.MX 8M Mini Development Kits")
