[PATCH 3/8] [ARM] U8500: adds mop500 platform

[srinidhi.kasagar@stericsson.com (srinidhi kasagar)]

From: srinidhi kasagar <srinidhi.kasagar@stericsson.com>

This adds mop500 target platform which is based
on U8500 architecture.The platform is based
on early drop silicon version of 8500.
By selecting this platform CPU_V7 and GIC are
enabled.
