[RFC PATCH] powerpc/numa: Return the first online node if device tree mapping returns a not online node

[Aneesh Kumar K.V]

numa_setup_cpu can return nodes that are not online. But setup_node_data()
only initialize NODE_DATA for only online numa nodes. Hence avoid returning
nodes that are not online.
