Add support to extract device name from device tree blob. If the property "dev-name" is set in the DTS this name will be used when creating the device. The auxdata_lookup has precedence and will override the "dev-name" property.
Adding support to parse DTS "dev-name" will make it possible to replace these kind of structures with a dev-name in the DTS.
