[PATCH v4 3/5] ARM: dts: sun9i: Enable USB support on A80 Optimus board

[Chen-Yu Tsai]

On the Optimus board, all three USB hosts can be used.
HCI0 and HCI2 are available through the USB connector.
HCI1 is available with HSIC through 2 pins on the GPIO
expansion header.

This patch also adds a regulator for HCI2/USB3's VBUS.
