sunxi: Enable usb ports on the Sinovoip BPI M3
DLDO3 is used to provide Port-D power and PD is used for the usb-hub / sata-5v enable pins. The 2.5V comes from the schematic and matches the factory image fex file. The dts changes are the minimal changes needed for u-boot to pick-up the usb host controllers. The upstream kernel does not (yet) have usb host support.
