Revert "visualizer: do not apply calibration on audio routed to afe proxy"

* Calibration with hardcoded AFE Proxy acdb_id (45), which is supposed
   to get rid of post-processing, is unnecessary and can cause sudden
   (and unpleasant) volume level change when HW visualizer is shown.
   (e.g. on lockscreen)

* The acdb_id doesn't change, and forces use of the same audio
   calibration for all devices (headphones/speaker/etc...).

This reverts commit 09990978.
