The OCEDO Raccoon only has one ethernet port, but currently uci sections
for WAN and LAN are created.
Additionally, newer versions of the devices U-Boot (units with SteelWRT)
set the kernel-cmdline and therefore overwrite the partition-layout.
We fix this by overwriting the cmdline supplied by the bootloader.
