net: allow sh_eth to get mac address through platform data
Extend the sh_eth driver to allow passing the mac address using the platform data structure. This to simplify board setup code. Signed-off-by: Magnus Damm <damm@opensource.se> Tested-by: Kuninori Morimoto <morimoto.kuninori@renesas.com> Signed-off-by: David S. Miller <davem@davemloft.net>
