ARM: dts: sun6i: hummingbird: Enable USB OTG
The A31 Hummingbird has a mini USB OTG port, and uses GPIO pins from the SoC for ID pin and VBUS detection and VBUS control. The PMIC can also do VBUS detection and control. Here we prefer to use the PMIC's DRIVEVBUS function to control VBUS for USB OTG, as that is the hardware default.
