Input: tsc40 - remove wrong announcement of pressure support
The tsc40 driver announces it supports the pressure event, but will never send one. The announcement will cause tslib to wait for such events and sending all touch events with a pressure of 0. Removing the announcement will make tslib fall back to emulating the pressure on touch events so everything works as expected.
