ucm2: HDA: Use Master volume control for dual speakers

alsa-project/alsa-ucm-conf pull request #410 was opened from tuxedoxt:

This PR extends the existing 'activate Bass Speaker' case with additional configuration

- Use Master mixer for volume control (instead of only using Speaker) - Configure Speaker Volume and Bass Speaker volume to max since Master volume regulation is used

It fixes a case where only the first speaker volume is changed using the system volume control.
