From: Sjoerd Simons <sjoerd.simons@xxxxxxxxxxxxxxx>
If the "linux,gpio-keymap" DT property is defined, the T19 keys are configured
and the device is setup as a touchpad rather than a touchscreen. The logic is
part of the input device initialization routine but it can be factored out to
its own function to simplify the former.
