RFC 1/1 Add support for Wacom W8001 penabled serial touchscreen

Hi Dmitry, linux-input,

Thanks for your previous feedback. I've made the improvements to drop the use of cmd mutex, expected packet, cleanup and report tilt events. Let me know your thoughts.

Thanks,
jaya

The Wacom W8001 sensor is a sensor device (uses electromagnetic resonance) and it is interfaced via its serial microcontroller to the host.
