[PATCH 6.12.y 1/2] ALSA: hda/realtek: Enable mute LEDs on HP OmniBook 7 17-dc0xxx

[Alexandr <youdoit@mail.ru>]

From: Jaeho Cho <jaeho2025@gmail.com>

commit 1c4f6202876a74e752a8cfd3696955f761671c7a upstream.

The HP OmniBook 7 Laptop 17-dc0xxx (SSID 103c:8d9c) has mute and
mic-mute LEDs on its F6 and F9 keys, but neither lights up. Its quirk
entry only sets up the two CS35L41 amplifiers, so no LED control is
registered for either key.

Writing to the ALC245 by hand with hda-verb, the mute LED responds to
COEF 0x0b bits 2-3 and the mic-mute LED to GPIO 0x04, lit when the pin
is low. That appears to match what ALC245_FIXUP_HP_X360_MUTE_LEDS
already does, so add a fixup that chains the two-amp I2C setup to it
and use it for this model.

Tested on 7.2.4 with the patched module: hda::mute and hda::micmute
are registered, and both LEDs follow the speaker and microphone mute
state, including from the F6 and F9 keys.
