Currently E500MC implies E500.  With this, E5500 would not imply E500
-- hence all the ifdefs with E500 || E5500 that this adds.  When would
we want to ifdef E500 or E500MC but not E5500?

Given how similar e500mc and e5500 are, I think we should just use
CONFIG_E500MC for it.  Any 32/64-bit distinctions would just check
CONFIG_PPC64, CONFIG_BOOK3E_64, or similar.
