[Impact]
The mic mute/audio mute LEDS are not work on
1) HP ZBook Fury 17.3 Inch G8 Mobile Workstation PC
2) HP ZBook Fury 15.6 Inch G8 Mobile Workstation PC
3) HP ZBook Studio 15.6 Inch G8 Mobile Workstation PC
4) HP EliteBook 855 G8 Notebook PC
The right channel of internal speaker doesn't work on
1) HP ZBook Fury 17.3 Inch G8 Mobile Workstation PC
2) HP ZBook Fury 15.6 Inch G8 Mobile Workstation PC
3) HP ZBook Studio 15.6 Inch G8 Mobile Workstation PC

[Fix]
These four platforms need specific quirk for different hardware layout.
Thus, add the quirks for them.

[Test]
After applying the quirk, the LEDs/function are work good on
1) HP ZBook Fury 17.3 Inch G8 Mobile Workstation PC
2) HP ZBook Fury 15.6 Inch G8 Mobile Workstation PC
3) HP ZBook Studio 15.6 Inch G8 Mobile Workstation PC
4) HP EliteBook 855 G8 Notebook PC

[Where problems could occur]
If HP ships the different system boards design with the same subsystem ID of audio codec which is using different GPIO pins (different layout), then the quirk will not work (LEDs/function will not work when muting audio-output or microphone).
