iio: hid-sensors: Add hinge sensor driver
The Hinge sensor is a common custom sensor on laptops. It calculates the angle between the lid (screen) and the base (keyboard). In addition, it also exposes screen and the keyboard angles with respect to the ground. Applications can easily get laptop's status in space through this sensor, in order to display appropriate user interface.
