[PATCH v6 3/4] mm: enable CONFIG_MOVABLE_NODE on non-x86 arches

From: Reza Arbab
Date: Mon Nov 07 2016 - 18:45:27 EST

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).
