configs: Unifiy interpretation of Realview mem_regions

In every arm platform which is making use of them, mem_regions are
interpreted as a pair of start address and size. However arm
SimpleSystem, which is using VExpress_GEM5_V1, is interpreting them as
start address and end address.  This patch is fixing this mismatch.
