[ARM] basic support for the Marvell Orion SoC family

The Marvell Orion is a family of ARM SoCs with a DDR/DDR2 memory
controller, 10/100/1000 ethernet MAC, and USB 2.0 interfaces,
and, depending on the specific model, PCI-E interface, PCI-X
interface, SATA controllers, crypto unit, SPI interface, SDIO
interface, device bus, NAND controller, DMA engine and/or XOR
engine.

This contains the basic structure and architecture register definitions.
