dt-bindings: input: touchscreen: st1232: add touch-overlay example 

The touch-overlay feature adds support for segments (touch areas) on the
touchscreen surface that represent overlays with clipped touchscreen
areas and printed buttons.

Add nodes for a clipped touchscreen and overlay buttons to the existing
example.
