[PATCH v3] ALSA: hda/realtek: Add mute and mic-mute LEDs for HP ENVY 16 (103c:8be5)

[Ajanesh Lal <ajaneshlal3@gmail.com>]

The HP ENVY Laptop 16-h1xxx (PCI SSID 103c:8be5) uses an ALC245 codec
with CS35L41 I2C speaker amplifiers. No LED fixup is applied for this
subsystem ID, so the speaker mute LED and the microphone mute LED are
never driven and do not follow their keys.

Add a fixup that calls the existing ALC245 mute LED COEF helper and the
GPIO mic-mute LED helper directly, then chains to the CS35L41 I2C
amplifier setup so the speakers keep working. Use it for 103c:8be5.

Tested on an HP ENVY Laptop 16-h1xxx running kernel 7.2.11: the
hda::mute and hda::micmute LEDs appear and follow their keys, and the
speaker amplifiers still bind (CS35L41 Bound in dmesg). The mic LED
GPIO pin and polarity are not verified on other hardware.

Changes in v3:
- Use real name in Signed-off-by and From.
- Add Fixes tag for the commit that added the quirk.
- Rebase onto sound.git for-next.
