    board: ge: bx50v3: move FEC MAC address programming to driver · cf678b31

    Instead of programming the hardware directly in the board
    implementation, follow the flow documented in doc/README.enetaddr: set
    the enet[0-9]*addr environment variable and let the driver program the
    hardware.
    
    This avoids duplicating the implementation as it already exists in the
    driver (drivers/net/fec_mxc.c: fec_set_hwaddr).
    
    The mapping from the driver's index to the environment variable's name
    is documented in README: Note for Redundant Ethernet Interfaces. It is
    assumed that eth_devices for the controllers on the board are always
    indexed in the same order, i.e. FEC always has the index 2.
    
    The FEC driver does *not* set the flag Set MAC Address on Transmit (bit
    set_eth0_mac_address used to do but this is unnecessary as the Linux
    networking stack fills in the MAC address.
