mm: enable CONFIG_MOVABLE_NODE on non-x86 arches
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).
