Add a proper Odroid-N2 board support to handle the Ethernet MAC address stored in the in-SoC eFuses.
This feature need to be implemented for all Amlogic SoC boards, since many boards link libretech-cc also generate random mac address for ethernet.
Please add my: Tested on N2. Tested-by: Anand Moon linux.amoon@gmail.com
