The otg_id line on the Quartz64 Model A is not connected to anything.
This prevents automatic selection of the dual role usb port. In otg mode
it defaults to device mode. Force it to host mode to retain previous
behavior.

Fixes: bc405bb3eeee ("arm64: dts: rockchip: enable otg/drd operation of usb_host0_xhci in rk356x")
