Audio: Extend GPIO jack detection support for all medfield based devices
BZ: 37120
Redridge device has a GPIO pin which can be used to detect high impedance
headsets.
With this GPIO support, whenever an insert interrupt is received and the
micbias value is out of range, it checks the GPIO pin and reports the jack as
a HEADSET if the GPIO pin says that there is a headset.
