reg was defined as one region covering the entire DP block, but the memory map is actually split in 4 regions and obviously the size of these regions differs between platforms.
Switch the reg to require that all four regions are specified instead. It is expected that the implementation will handle existing DTBs, even though the schema defines the new layout.
