Yes, that is this patch set's purpose. Just need below steps to do smooth
migration.
1. allow memory-region-name as options for binding
2. update driver to parse memory-region-names
3. update all dts to add memory-region-names
4. remove old Node name code and change binding to force memory-region-names
