[PATCH 4/4] ARM: dts: sun8i: enable USB OTG on Orange Pi One board

[Icenowy Zheng]

Orange Pi One board features a USB OTG port, which cannot be used to
power up the board, but have a gateable VBUS and an ID pin, which makes
it possible to be used in both host and peripheral mode.

Enable its OTG port in dual-role mode.
