ASoC: cs35l56: Log SoundWire status updates only on changes

Browse Source 
The SoundWire slave update_status() callback can be invoked when the
status has not changed. To prevent large amounts of log noise with debug
enabled, log them only when the status changes. This also helps with
understanding them, because they now log an actual change in state.
