Since memory node names are not constrained by the binding, incorrect names can silently pass DT validation, as seen in examples using "vdevbuffer" instead of "vdev0buffer" ([1] and [2]). Add memory-region-names to explicitly identify the expected memory regions and avoid relying on memory node names as ABI.
