sata_mv: mbus decode window support
Make it possible to pass mbus_dram_target_info to the sata_mv driver via the platform data, make the sata_mv driver program the window registers based on this data if it is passed in, and make the Orion platform setup code use this method instead of programming the SATA mbus window registers by hand.
