Add a common touchscreen optional property that will specify the minimum pressure applied to the screen that is needed such that the driver will report the touch event.

Why do we move from the pattern and call it trheshold and not touchscreen-min-pressure?
- touchscreen-fuzz-x : horizontal noise value of the absolute input device (in pixels) - touchscreen-fuzz-y : vertical noise value of the absolute input -- 2.7.4
