Build break fix for SPLPAR=n builds and CPU hotplug.

arch/powerpc/platforms/pseries/hotplug-cpu.o: In function `.dlpar_online_cpu':
hotplug-cpu.c:(.text+0xc40): undefined reference to `.find_and_online_cpu_nid'

Move the declaration of find_and_online_cpu_nid() to topology.h where
we can define it as a no-op for SPLAPR=n builds.
