sound: Add a new stop_play() method
At present there is no positive indication that U-Boot has finished sending sound data. This means that it is not possible to power down an audio codec, for example. Add a new method that is called once all sound data has been sent. Add a new method for this, called when the sound_play() call is done. Signed-off-by: Simon Glass <sjg@chromium.org>
