Revert "audio: Update mixer paths for open source HAL"

Switch back to proprietary audio HAL

* The open source HAL works perfect for media,
  but in-call audio is wonky.
* Because let's rather have the phone part of our smartphones
  work perfectly.

This reverts commit f749720caa02c0ace62903b8c709555ae155fa40.
