boards: ls1046ardb: disable unavailable "ethernet" node in dts
Linux device tree contains "ethernet" node for all possible
interface supported by SoC i.e. LS1046A.
It is not necessary for a SerDes protocol to support all possible
interface. So disable unavailable "ethernet" node in device tree.
Also, enable FDT_SEQ_MACADDR_FROM_ENV to fetch MAC address
sequentially from environment variables
