[Impact]
The mic mute/audio mute LEDS are not work on
1) HP Elite Dragonfly G2 Notebook PC
2) HP EliteBook x360 1040 G8 Notebook PC
3) HP EliteBook 840 Aero G8 Notebook PC
4) HP ZBook Power 15.6 inch G8 Mobile Workstation PC
The right channel of internal speaker doesn't work on
1) HP Elite Dragonfly G2 Notebook PC
2) HP EliteBook x360 1040 G8 Notebook 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/speaker are work good on
1) HP Elite Dragonfly G2 Notebook PC
2) HP EliteBook x360 1040 G8 Notebook PC
3) HP EliteBook 840 Aero G8 Notebook PC
4) HP ZBook Power 15.6 inch G8 Mobile Workstation 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/speaker will not work when muting audio-output or microphone).
