devicetree: replace 'zephyr,touch' chosen property with DT alias 'touch'

'zephyr,touch' chosen property is currently used only by the
subsys/input/draw_touch_events sample and not used by any upstream
Zephyr driver, subsystem, or module. Hence it is not justified to have
this chosen property as it only creates confusion and leads users to
wrongly assume that setting this property produces some effect in
Zephyr internals.
