This makes changes so the u-boot dts file is structured more similar to the mainline linux dtsi file. It provides a minimal common dts that can work for most boards based on the ClearFog platform. Ethernet support is only supported for eth0 however all devices are left enabled so u-boot can generate and provide mac addresses for all of the network interfaces.
