board: traverse: ten64: set serial# to be 'label' MAC
The GE0 (first Gigabit Ethernet interface) is used as the 'serial number' for the board and appliance. To ensure the 'true' board S/N is available regardless of how the DPAA2 subsystem is configured, use serial# so it is passed in the device tree.
