Subject: [PATCH] arm64: dts: rockchip: Fix SoQuartz CM4IO usb

The SoQuartz CM4-IO should support otg mode, however it currently
defaults to device mode when otg is enabled. Force it to host mode to
retain the previous behavior.

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