Rationalised the ARM Platform code.

We now have separate targets for the GEM5 VE and FVP VE, as the GEM5 version
actually simulates an A15, and has a few quirks. The FVP VE and Pandaboard
targets share most of their code. Thus we've got three ARMv7-A targets now,
and it should be easy to add more, as soon as we've got the simulators.
