[Impact]
The mic mute/audio mute LEDS are not work on
1) HP ProBook 630 G8 Notebook PC
2) HP ProBook 445 G8 Notebook PC
3) HP ProBook 450 G8 Notebook PC

[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).
