quirks: touchpad: add ModelPressurePad

Browse source 
Unlike in traditional touchpads, whose pressure value equals contact
size, on pressure pads pressure is a real physical axis.

We don't take advantage of the pressure information reported by
pressure pads yet, so we disable it to avoid errors.

Add a new model quirk for pressure pads instead of disabling
ABS_MT_PRESSURE and ABS_PRESSURE.
