Image a board that doesn't want all CPU (SoC) interfaces to get initialized. 
If for such a board a cpu-specific init routine exists, there is no chance to 
not enable (init) all those cpu interfaces as done in cpu_eth_init().

With this approach of mutually exclusive routines, it could define it's 
board_eth_init() and init only the Soc interfaces really needed. Plus 
additional ones of course.

Does this make sense?

Best regards,
Stefan
