[Impact]
The mic mute/audio mute LEDS are not work on
1) HP ProBook 440 G9 Notebook PC
2) HP ProBook 450 G9 Notebook PC
3) HP EliteBook 640 G9 Notebook PC
4) HP EliteBook 650 G9 Notebook PC

[Fix]
Cherry picked below commit from v5.17.0-rc8
e6194c8d06 ALSA: hda/realtek: fix right sounds and mute/micmute LEDs for HP machines

[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).
