ARM: shmobile: armadillo800eva: Reference DT implementation

Provide alternate board code for the Armadillo800EVA to demonstrate how
DT may be used given the current state of driver device tree support.
This is intended to act as a reference for mach-shmobile developers.

This a rather bare bone version with the following devices supported:

 - GIC
 - irqpins
 - i2c0/1
 - touchscreen
