dev-arm: Add VExpress_GEM5_Foundation platform

Browse Source 
A new VExpress_GEM5_Foundation platform has been added in order to match
the FVP Armv8-A Foundation Platform described in:

Armv8-A Foundation Platform - User Guide - Version 11.8

The VExpress_GEM5_V1/V2 are already loosely based on the Foundation
platform, however there are some differences in the PCI regions (V1/V2)
and the GICv3 regions (V2).
We hence introduce the VExpress_GEM5_Foundation to match closely the
FVP Foundation Platform
