[PATCH] ARM: dts: sun9i: Enable USB support on Cubieboard4

[Mark Kettenis <kettenis@xxxxxxxxxxx>]

On the Cubieboard4 HCI0 is directly connected to a USB connector,
and HCI2 is connected to a USB hub on the board.  HCI1 is available
with HSIC throug 2 pins on the GPIO expansion header, but left
disabled just like on the Optimus board.

This patch also adds the VBUS regulators.
