ALSA: hda/cirrus: Set Initial DMIC volume for Bullseye to -26 dB

BugLink: https://bugs.launchpad.net/bugs/1923557
After booting for first time on Bullseye, the DMIC is currently muted.
Instead, the DMIC volume should be set to a valid initial value.

Tested on DELL Inspiron-3505, DELL Inspiron-3501, DELL Inspiron-3500
