From: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>
Currently the timeout for SoundWire individual transactions is 2s.
This is too large in comparison with the enumeration and completion timeouts used in codec drivers.
A command will typically be handled in less than 100us, so 500ms for the command completion is more than generous.
