[Impact]
Framework PTL platform with Realtek ALC295 audio solution will have audio recording quality when the input volume is configure > 50%.

[Fix]
Fix by backporting the commit: 67c738152207 ("67c738152207") which fix mic boost on particular SSIDs of the Framework machines

[Test Case]
1. Boot up the machine of new Framework PTL platforms with Realtek ALC295 audio solution
2. Go to g-s-d and select sound --> input (Internal Microphone) --> Adjust the input volume > 50%
3. Do `arecord` with the internal microphone and play the recorded clips.

[Where problems could occur]
It only limit the mic boost based on particular SSIDs. The risk of regression is limited.
