touch_ret_t touch_qt_sensor_config(touch_qt_grp_t touch_qt_grp,
This API configures a single QTouch Key, Rotor or Slider.
The user must provide all the sensor specific settings as input to this API.
Rotor / Slider sensor will occupy contiguous channels from from_channel to to_channel.
For QTouch acquisition method, 3 Touch channels per rotor / slider are supported. Keys
are always formed using 1 Touch channel.
