ARM: kirkwood: Add support for RaidSonic IB-NAS6210/6220 using devicetree
Add support for the IB-NAS6210 and IB-NAS 6220. Describe as much as currently possible in the devicetree files, including the NAND partitions. Use the partition scheme of the original firmware by default. Create a board-ib62x0.c for everything else.
