[PATCH 07/37] powerpc: call no-longer static setup_nr_cpu_ids instead of replicating it

[Milton Miller]

c1854e00727f50f7ac99e98d26ece04c087ef785 (powerpc: Set nr_cpu_ids early
and use it to free PACAs) copied the formerly static setup_nr_cpu_ids
from init/main.c but 34db18a054c600b6f81787165669dc572fe4de25 (smp:
move smp setup functions to kernel/smp.c) moved it to kernel/smp.c
with a declaration in include/linux/smp.h, so we can call it instead of
replicating it.

I found this cleanup while c1854e was being merged, but saved it from the
end to ease backporting.
