To support movable memory nodes (CONFIG_MOVABLE_NODE), at least one of
the following must be true:
1. We're on x86. This arch has the capability to identify movable nodes
at boot by parsing the ACPI SRAT, if the movable_node option is used.
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).
