[PATCH kernel] powerpc/pseries: Fix compile of memory hotplug without CONFIG_MEMORY_HOTREMOVE

[Alexey Kardashevskiy <aik@ozlabs.ru>]

51925fb3c5 "powerpc/pseries: Implement memory hotplug remove in the kernel"
broke compile when CONFIG_MEMORY_HOTREMOVE is not defined due to missing
symbols. This fixes the issue by adding the missing symbols.

This is made against ad30cb99465 (mpe/next) and can be squashed into 51925fb3c5
if not too late.
