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?

Stefan
