Some devices don't use the builtin jack-detect but can still benefit from the mic-bias-current over-current-detection headphones vs headset detection done by rt5640_detect_headset().
In this case the jack-inserted check done by rt5640_detect_headset() needs to be done through a GPIO rather then by using the codec's builtin jack-detect. Add an optional hp_det_gpio parameter and export rt5640_detect_headset() for use on machines where jack-detect is handled outside of the codec.
