ARM: initial DTS support for km_kirkwood
This is a first attempt to support the km_kirkwood reference design with a device tree. This km_kirkwood design is present in many Keymile products. It is based on the Marvell Bobcat SOC which integrates a Kirkwood CPU next to a big L2 Ethernet Switch. The Kirkwood in the SOC is very similar to the "normal" one, but there are a few differences. This initial support is minimal: the kernel can boot with network (ge0), serial port and NAND functional.
