With soft volume control function, rt5645/rt5650 will start with 0dB
volume and take a little time to adjust volume to given value. And it
will cause a bad user experience. This patch disable it.

This seems like something that it'd be better to give users control over
- some users will be annoyed by a soft ramp but there will be others who
