[PATCH] ARM: dts: imx53: add support for USB armory board

From: Andrej Rosano <andrej at inversepath.com>

Add support for Inverse Path USB armory board, an open source
flash-drive sized computer based on Freescale i.MX53 SoC.

http://inversepath.com/usbarmory

As the device can work in either USB device mode or USB host mode,
two different device tree file are needed along with one common
include file.
