audio: update FM tables

Change notes:
1. Enable L/R downmixer and duplicator for iS900, which results in same L/R output.
2. T6+K6 tuning for echo leak as attached mail.

Changed use cases:
T6:
   HANDSFREE-HANDFREE, idx 0x20
   HANDSFREE-PORTRAIT, idx 0x21
   HANDSFREE-REVERSED_LANDSCAPE, idx 0x22
   HANDSFREE-REVERSED_PORTRAIT, idx 0x23
   HANDSFREE-CHARGING_ONLY, idx 0x24
T6+K6:
   HEADSET-DOCK, idx 0x6B
