powerpc/pseries/cmm: Rip out memory isolate notifier
The memory isolate notifier was added to allow to offline memory
blocks that contain inflated/"loaned" pages. We can achieve the same
using the balloon compaction framework.
Get rid of the memory isolate notifier. Also, we can get rid of
cmm_mem_going_offline(), as we will never reach that code path now
when we have allocated memory in the balloon (allocated pages are
unmovable and will no longer be special-cased using the memory
isolation notifier).
Leave the memory notifier in place, so we can still back off in case
memory gets offlined.
