ASoC: rt1316: fix key tone missing

Browse Source 
This patch adds a control that there are three options to control the digital volume output.
The user could select "immediately" to make volume updates immediately
and avoid key tone missing issues.
In default, the driver selects that the volume update when a zero-crossing with a soft ramp.
