ax88796: Add method to take MAC from platform data
Implement a way to provide the MAC address for ax88796 devices from their platform data. Boards might decide to set the address programmatically, taken from boot tags or other sources. Signed-off-by: Daniel Mack <daniel@caiaq.de> Signed-off-by: David S. Miller <davem@davemloft.net>
