arm: mvebu: Better align Clearfog dts file with Linux kernel

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.
