As with previous generations of this device (see https://patchwork.kernel.org/patch/7887361/), the ITE
HID Sensor Hub, responsible for the accelerometer and als sensor, requires a quirk entry.
Without the entry, the Sensor Hub can't be accessed and the kernel fails to report any movements. As a result
iio-sensor-proxy receives no new data.
It shall additionally be noted that the i2c-hid 'sleep' bug (present since kernel ver. 4.3)
still affects the driver. This means that the sensor hub will not report any movement, until
the device is suspended and resumed.
