Maybe we could take this opportunity to clean up the CPU selection in
Kconfig and use select instead... right now we have a mess like

config 440GP
        bool
        depends on EBONY
        default y

config 440
        bool
        depends on 440GP || 440SP || 440SPE || 440EP
        default y

etc... -- it would be nice for this to look like

config EBONY
	bool
	select 440GP

config 440GP
	bool
	select IBM_NEW_EMAC_ZMII
	select 440

config 440
	bool

I'm happy to do this cleanup after things settle down though
