[PATCH] ALSA: hda/realtek: Add mute LED quirk for HP OMEN 15-ax

[Xavier Goffin <xaviergoffin42@gmail.com>]

On the HP OMEN 15 ax-202nf, the keyboard mute LED is exposed through
NID 0x1b rather than 0x18. This reuses the existing quirk
(ALC269_FIXUP_HP_MUTE_LED_MIC3) to allow the keyboard LED to reflect
the built-in speaker mute state.

Tested on HP OMEN 15 ax-202nf with Realtek ALC295:
- hda::mute/brightness properly follows mute state
- mute/unmute via keyboard shortcut or via GUI volume control
- state is kept on suspend & resume, and reboot
- plugging a 3.5mm jack headset reflects the headset mute status
- unplugging reverts the LED to the speaker mute status
- USB/Bluetooth headsets are not covered
