[PATCH] arm/dt: Add ST-Ericsson u8500 device tree support

Adds support for passing a device tree for booting the u8500 board.

Signed-off-by: Grant Likely <grant.likely at secretlab.ca>

Completely untested.  Not even compiled.  Per, this should be all you
need to change in the kernel to get DT support working on the u8500.
