CONFIG_SMP_750 doesn't exist in Kconfig, therefore removing all
references for it from the source code.

Yeah, we don't support SMP on 750 at the moment.  This code was carried over
from the arch/ppc days, and that code was present pre-git.  I think we can
drop it, but I'll leave that up to Ben.  Maybe he has crazy plans for a 750 SMP
board.

Nope :-) Though it would be nice to also remove the call sites too and
thus remove the macro entirely.

Cheers,
Ben.
