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.
