herolte: use communication-* paths for voice recording

    * When trying to make a WhatsApp voice call, or recording a vocal
      message, or when trying to do the same with Telegram or any other
      VoIP app, the OSS audio HAL select respectively the
      earpiece-{speaker,headset}-mic paths for setting up the
      microphone. Previously, we were using the media-{headset}-mic
      paths from stock, which is virtually wrong as the stock 8890 HAL
      for doing such operations is selecting the communication-* paths,
      which makes sense since the respective gains of those paths are
      higher. This fixes the issue people had when doing speakerphone
      VoIP calls that the other side wasnt able to hear any sound, and
      is better than the previous solution which was basically randomly
      increasing the gains until the other side was able to hear
      something
