arm/dt: vexpress: add basic DT platform matching support
This patch adds a DT match table to the Versatile Express machine
description in order to enable basic device tree support.
Tested on a Versatile Express board where the device tree blob is
passed to the kernel by u-boot.

[converted .dts file to use skeleton.dtsi, and added 'dtbs' targets]
