soundwire: bus: squelch error returned by mockup devices
All read and writes from/to SoundWire mockup devices will return -ENODATA/Command_Ignored, this patch forces a Command_OK result to let the bus perform the required configurations, e.g. for the Data Ports, which will only have an effect on the Master side.
