[PATCH v2] ALSA: hda/conexant: Add quirk for Acer Aspire Go 16 mic mute LED

[PATCH v2] ALSA: hda/conexant: Add quirk for Acer Aspire Go 16 mic mute LED

[Gonçalo Miranda]

The Acer Aspire Go 16 (AG16-71P) uses a Conexant SN6180 codec
(subsystem ID 0x1025:0x1937) with the microphone mute LED wired
to GPIO4. Add a quirk entry so the kernel drives the LED in sync
with the microphone mute state.

The fixup reuses the existing cxt_setup_mute_led() helper with
mask 0x10, matching the behavior verified on the hardware.

Changes in v2:
- Moved the quirk entry to the correct position in PCI SSID sort
  order, as requested by Takashi Iwai.

Applied to for-next branch now.  Thanks.
