[PATCH v2] ALSA: hda/realtek: Add mute LED quirk for HP 250 G8 (0x85f3)

[Bramwel Barack <bramwelbarack89@gmail.com>]

The HP 250 G8 Laptop PC (subsystem 103c:85f3) using the Realtek ALC236
codec requires a specific quirk to enable the mute button LED.
Currently, the audio mutes in software, but the physical indicator
light remains unlit.

Adding a quirk entry to the alc236_fixup_tbl with the
ALC236_FIXUP_HP_MUTE_LED_COEFBIT2 fixup correctly maps the
LED to the mute state via COEF index 0x07.

v2:
 - Added technical description of the COEF bit mapping.
 - Fixed spacing error in the quirk entry.
 - Updated mailing list to linux-sound@vger.kernel.org.
