of_node_to_nid and dump_numa_cpu_topology are declared inline in their
respective header files, if CONFIG_NUMA is not set. Thus it is only
valid to define these functions in numa.c if CONFIG_NUMA is set.
(numa.c, despite the name, isn't conditionalized on CONFIG_NUMA, but
CONFIG_NEED_MULTIPLE_NODES.)
