memory_hotplug: allow online/offline memory to result movable node
Now, memory management can handle movable node or nodes which don't have
any normal memory, so we can dynamic configure and add movable node by:
online a ZONE_MOVABLE memory from a previous offline node
offline the last normal memory which result a non-normal-memory-node
movable-node is very important for power-saving, hardware partitioning and
high-available-system(hardware fault management).
