This adds a driver for touchscreens using the zforce infrared
technology from Neonode connected via i2c to the host system.

It supports multitouch with up to two fingers and tracking of the
contacts in hardware.

changes since v1:
- address comments from Dmitry Torokhov
  but I kept the access_mutex due to the possible race I described in the
mail:
  - touch -> interrupt
  - isr reads first packet
  - user closes device -> stop command sent
  - isr reads payload
- address comments from Henrik Rydberg, letting the input system collect
  singletouch from the multitouch data using the appropriate functions
ping?


Thanks
Heiko
