iio: hid-sensor-rotation: Add relative orientation sensor hid support
Relative orientation(AG) sensor is a 6dof orientation sensor, it depends on acceleration and gyroscope sensor data. It gives a quaternion describing the orientation of the device relative to an initial orientation. It is a standard HID sensor. More information can be found in: http://www.usb.org/developers/hidpage/HUTRR59_-_Usages_for_Wearables.pdf Relative orientation(AG) sensor and dev rotation sensor have same channels and share channel usage id. So the most of the code for relative orientation sensor can be reused.
