[PATCH v3 2/3] ALSA: hda/realtek: Enable headset mic of Acer C20-820 with ALC269VC

[Jian-Hong Pan]

The Acer Aspire C20-820 AIO's audio (1025:1065) with ALC269VC can't
detect the headset microphone until ALC269VC_FIXUP_ACER_HEADSET_MIC
quirk maps the NID 0x18 as the headset mic pin.

    Realtek's suggestion
