ALSA: ASoc: DaVinci Delay start of ASP to trigger

Browse Source 
Since only 4 mainline ASoC codecs support the trigger
callback, we cannot rely upon them stopping the frame clock
if they are master and must assume it is running even if the
sound is paused. Thus we cannot start the ASP until the trigger
method.
