FBC was disabled on TGL due to random underruns. It has
been determined that FBC will not work reliably with PSR2.
This series re-enables fbc along with taking care of the
PSR2 limitations for TGL.

Bspec: 50422 HSD: 14010260002

v2: Addressed review comments and added bspec links

v3: Addressed Ville's review comments

v4: Change the WA as per Jose's recommendation.
