drivers/net: Check "ethernet_mac" when the device index is 1
It is a special case for the Fizz firmware branch, when the device index
is 1, it will check "ethernet_mac" first and then "ethernet_mac0".
For single NIC: config.device_index = "1", maps to "ethernet_mac"
For multiple NICs: config.device_index = "1", maps to "ethernet_mac0"
BUG=b:77836343
BRANCH=Fizz
TEST=Add device index in device tree &&
Program the mac address to VPD in shell
vpd -s ethernet_mac=<mac address> or
vpd -s ethernet-mac[0-9]=<mac address> && reboot the system.
Ensure the MAC address was fetched correctly by ifconfig command.
