[v2,3/3] ARM: dts: sun8i: enable USB OTG on Orange Pi One

Commit Message

Orange Pi One features a MicroUSB port that can work in both host mode
and peripheral mode.

When in host mode, its VBUS is controlled via a GPIO; when in peripheral
mode, its VBUS cannot be used to power up the board.

Add support for this port.
