[Impact]
The Mute/Mic-mute LEDs are not work when muting audio-output/microphone on HP 850/840/440 G8 laptops.

[Fix]
Add three realtek quirks for them.

[Test]
After applying the quirks, the LEDs are functioned on HP 850/840/440 G8 laptops.

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