Subject: [PATCH] MIPS: Octeon: Enable interfaces on EdgeRouter Lite

Enable interfaces on EdgeRouter Lite. Tested with cavium_octeon_defconfig
and busybox shell. DHCP & ping works with eth0, eth1 and eth2.

The board type "UBNT_E100" is taken from the sources of the vendor kernel
shipped with the product.
