MIPS: Alchemy: Add au1000-eth platform device

Browse Source 
This patch makes the board code register the au1000-eth platform device. The
au1000-eth platform data can be overriden with the au1xxx_override_eth_cfg
function like it has to be done for the Bosporus board which uses a
different MAC/PHY setup.
