soundwire: cadence: reduce timeout on transactions
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.
