To create a movable node, we need to hotplug all of its memory into ZONE_MOVABLE.
Note that to do this, auto_online_blocks should be off. Since the memory will first be added to the default zone, we must explicitly use online_movable to online.
Because such a node contains no normal memory, can_online_high_movable() will only allow us to do the onlining if CONFIG_MOVABLE_NODE is set. Enable the use of this config option on PPC64 platforms.
