Add a new function to the eth_device struct for programming a network controller's hardware address.
After all network devices have been initialized and the proper MAC address for each has been determined, make a device driver call to program the address into the device. Only device instances with valid unicast addresses will be programmed.
This is a significant departure from existing U-boot behavior, but costs very little in startup time and addresses a very common complaint among developers.
