mb/google: Reduce DA7219 mic detect threshold to 200ohm The original DA7219 is designed to use a 500ohm mic detection threshold. Some headset mics (e.g. Logitech H111) have a lower DC impedance that is lower than the threshold and thus cannot be detected. Lower the threshold to 200ohm to match the new default value provided by Renasas as in https://patchwork.kernel.org/project/alsa-devel/patch/20231201042933.26392-1-David.Rau.opensource@dm.renesas.com/ to support such headsets.
