ALSA: hda/cirrus: Use CS8409 filter to fix abnormal sounds on Bullseye

Browse source

Cracking noises have been reported on the built-in speaker for certain
Bullseye platforms, when volume is > 80%.

This issue is caused by the specific combination of Codec and AMP in
this platform, and cannot be fixed by the AMP, so indead must be fixed
at codec level, by adding attenuation to the volume.

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