MIPS: au1000_eth: Get ethernet address from platform_data
au1000_eth uses firmware calls to get a valid MAC address, and changes it depending on platform device id. This patch moves this logic out of the driver into the platform device registration part, where boards with supported chips can use whatever firmware interface they need; the default implementation maintains compatibility with existing, YAMON-based firmware.
