[PATCH v3 1/2] arm: dts: arm: add arm corstone500 device tree

Corstone500[0] is a platform from arm, which includes Cortex-A cores and
ideal starting point for feature rich System on Chip (SoC) designs
based on the Cortex-A5 core.

These device trees contains the necessary bits to support the
Corstone 500 FVP (Fixed Virtual Platform) and the
FPGA MPS3 board.
