[Impact]
The mic mute/audio mute LEDS are not work on
1) HP EliteBook x360 830 G9
2) HP EliteBook 830 G9
3) HP EliteBook 840 G9
4) HP EliteBook 860 G9
5) HP EliteBook 840 Aero G9
6) HP EliteBook x360 840 Aero G9

[Fix]
It needs the specific quirk for the hardware layout.
Thus, add the quirks to make it works.

[Test]
After applying the quirk, the audio/mic mute LEDs are working good.

[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 will not work when muting audio-output or microphone).
