The LED is connected to GPIO3 of the Realtek ALC256 codec. Add a quirk entry using ALC256_FIXUP_ACER_SFG16_MICMUTE_LED, which configures GPIO3 (bitmask 0x04) as the micmute LED, identical to the Acer Swift SFG16. Tested by manually sending HDA verb commands directly to the codec and verifying that GPIO3 drives the LED while GPIO1 and GPIO2 do not.
