ARM: Add Support for Marvell Pantheon Familiy SoCs

Pantheon Family processors are highly integrated SoCs
based on Sheeva_88SV331x-v5 PJ1 cpu core.
Ref:
http://www.marvell.com/products/processors/communications/marvell_pantheon_910_920_pb.pdf

SoC versions Supported:
1) PANTHEON920          (TD)
2) PANTHEON910          (TTC)
