soundwire: extend SDW_SLAVE_ENTRY
The SoundWire 1.2 specification adds new capabilities that were not present in previous version, such as the class ID. To enable support for class drivers, and well as drivers that address a specific version, all fields of the sdw_device_id structure need to be exposed. For SoundWire 1.0 and 1.1 devices, a wildcard is used so class and version information are ignored.
