Description: SoundWire Slave status
These properties report the Slave status, e.g. if it
is UNATTACHED or not, and in the latter case show the
device_number. This status information is useful to
detect devices exposed by platform firmware but not
physically present on the bus, and conversely devices
not exposed in platform firmware but enumerated.
