To support movable memory nodes (CONFIG_MOVABLE_NODE), at least one of the following must be true: 1. This config has the capability to identify movable nodes at boot. Right now, only x86 can do this. 2. Our config supports memory hotplug, which means that a movable node can be created by hotplugging all of its memory into ZONE_MOVABLE. Fix the Kconfig definition of CONFIG_MOVABLE_NODE, which currently recognizes (1), but not (2).
