[PATCH v2 2/2] of, numa: Fetch empty NUMA node ID from distance map

[Gavin Shan]

There is no device node for the empty NUMA node. However, the
corresponding NUMA node ID and distance map is still valid in
"numa-distance-map-v1" compatible device node.

This fetches the NUMA node ID and distance map for these empty
NUMA node from "numa-distance-map-v1" compatible device node.
