MIPS: Alchemy: Define eth platform devices in the correct order
Currently, the eth devices are probed in the inverse order, first
au1xxx_eth1_device and then au1xxx_eth0_device. On the GPR board,
this makes trouble:
# ifconfig|grep HWaddr
eth0 Link encap:Ethernet HWaddr 00:50:C2:0C:30:01
eth1 Link encap:Ethernet HWaddr 66:22:01:80:38:10
A bogous ethernet hwaddr is assigned to the first device and
au1xxx_eth0_device is mapped to eth1, which even does not work
properly. With this patch, the problems are gone:
# ifconfig|grep HWaddr
eth0 Link encap:Ethernet HWaddr 66:22:11:32:38:10
eth1 Link encap:Ethernet HWaddr 66:22:11:32:38:11
