[PATCH v5 4/4] dt-bindings: input: touchscreen: st1232: add touch-overlay example

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

The st1232 driver supports the overlay-touchscreen and overlay-buttons
objects defined in the generic touchscreen bindings and implemented in
the touch-overlay module.

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