Add devicetree bindings and a driver for the Wacom W9000-series penabled
touchscreens.
The driver currently only contains the information for the W9002 and
W9007A, which I or Ferass could test on devices. It should also work with
other chips, such as W9001 or W9010. However, I couldn't test it on these
and the message length would need to be added.
