FVP: Always assume shifted affinity with MT bit
At present, the MPIDR validation on FVP relies on MT bit set along with shifted affinities. This currently is additionally dependent on the FVP model being of variant C. This however should be based on the presence of MT bit alone. This patch makes the change to always assume that the affinities are shifted in the FVP model when MT bit is present.
