Linus Walleij fa6e2eec15 ARM: realview: basic device tree implementation
This implements basic device tree boot support for the RealView
platforms, with a basic device tree for ARM PB1176 as an example.

The implementation is done with a new DT-specific board file
using only pre-existing bindings for the basic IRQ, timer and
serial port drivers. A new compatible type is added to the GIC
for the ARM1176.

This implementation uses the MFD syscon handle from day one to
access the system controller registers, and register the devices
using the SoC bus.

RealView boards other than PB1176 have the RAM available at
0x70000000, 256MB of which being mirrored at 0x00000000. If
the board supports 512MB of RAM, this option allows the
memory to be accessed contiguously at the high physical
offset. On the PBX board, disabling this option allows 1GB of
RAM to be used with SPARSEMEM.
