Add Pressure Calibration for Cyan
This CL adds in an initial pressure Calibration and a tweak
to make the edges of the touchpad work better with the gestures
library as well as allowing lighter taps.
BUG=chrome-os-partner:41302
TEST=manually installed on a Cyan, the touchpad seems to work well
with the changes.
