powerpc/pseries: Fix CONFIG_NUMA=n build

The build is failing with CONFIG_NUMA=n and some compiler versions:

  arch/powerpc/platforms/pseries/hotplug-cpu.o: In function `dlpar_online_cpu':
  hotplug-cpu.c:(.text+0x12c): undefined reference to `timed_topology_update'
  arch/powerpc/platforms/pseries/hotplug-cpu.o: In function `dlpar_cpu_remove':
  hotplug-cpu.c:(.text+0x400): undefined reference to `timed_topology_update'

Fix it by moving the empty version of timed_topology_update() into the
existing #ifdef block, which has the right guard of SPLPAR && NUMA.

Fixes: cee5405d ("powerpc/hotplug: Improve responsiveness of hotplug change")
