Support Headset Mic on HP cPC

[Kai-Heng Feng]

[Impact]
Two HP workstations can't detect headset microphone.

[Fix]
Apply vendor-specific coefficient to enable headset mic detection.

[Test]
Plug headset and see if the mic gets detected.
Headset mic gets detected correctly after applying the patch.

[Regression Potential]
Low. The fix matches to very specific machines, so all other systems are unaffected.
