[RFC PATCH 13/14] ARM: vexpress: Definition of vexpress dts specification

[Lorenzo Pieralisi]

The device tree methodology requires a dts file to be defined per
platform in order to describe the platform address space and topology,
in short the device tree in source format.

This patch adds the dts file for the Versatile Express board.
Some device names are still temporary and non-compliant waiting for the
definition of proper clock bindings.
