Bug description:
  [Impact]
  On one of the latest Lenovo laptops, the trackpoint doesn't work, we
  consulted apls guys, they said this trackpoint is different from others,
  it is a trackpoint-only device, so the current alps.c doesn't support it
  well, while the trackpoint.c can drive it well.

  [Fix]
  Check if it is trakcpoint-only device, if it yes, let trackpoint.c
  handle it.

  [Test Case]
  apply this patch and boot with the kernel, the trackpoint can work
  well.

  [Regression Risk]
  Low. the way of detect trackpoint-only alps device is provided by
  alps. so it is pretty safe.
