These id values should be same in machine driver and topology file, then 
only dailink can create without an error.
Always new be_id should add at the end only.

In this case BT_BE_ID should be at the end.

   enum be_id {
       HEADSET_BE_ID = 0,
       AMP_BE_ID,
       DMIC_BE_ID,
       BT_BE_ID,
   }
