[PATCH 4/4] dt-bindings: input: touchscreen: st1232: add example with ts-virtobj

[Javier Carrasco <javier.carrasco@wolfvision.net>]

The st1232 driver supports the virtual-touchscreen and virtual-buttons
objects defined in the generic touchscreen bindings and implemented in
the ts-virtobj module. Add an example where nodes for a virtual
touchscreen and virtual buttons are defined.
