[PATCH] ARM: dts: imx5: Add dts files for USB armory.

[vagrant@debian.org (Vagrant Cascadian)]

Add support for the USB armory board by Inverse Path. This board
features a Freescale iMX53 SoC, 512MB RAM, and USB OTG operating in
either peripheral or host mode, and 5 GPIO pins.

One .dtb is generated for operating in peripheral mode, and one is
generated for operating in host mode.
