bugfix: motion events with absolute coordinates are now merged correctly

Problem: On merge of events with absolute coordinates the
         coordinates of previous events are just overwritten. When
         merging a sequence of X and Y motion events, the x-component
         is ignored as it is overwritten by the y-event.

Solution: Initialize absolute coordinates with invalid value -1. Check
          if a coordiante is invalid before overwriting.
Merge branch 'hid-multitouch' into toughpad
allow for USB 3.0 support in run srcipts
staticaly map the absolute output from the touchpad to screen resolution
