Subject: [PATCH net-next 2/3] net: fec: remove fec_set_mac_address() from fec_enet_init()

The fec_enet_init() is only invoked when the FEC driver probes, and
the network device of FEC is not been brought up at this moment. So
the fec_set_mac_address() does nothing and just returns zero when it
is invoked in the fec_enet_init(). Actually, the MAC address is set
into the hardware through fec_restart() which is also called in the
fec_enet_init().
