The goodix touchscreen driver has gained support for the
optional touchscreen-inverted-x, touchscreen-inverted-y
and touchscreen-swapped-x-y properties as described in
Documentation/devicetree/bindings/input/touchscreen/touchscreen.txt.

Document these properties in the goodix bindings description.
