lvgl: Add default input device configuration option

Add the ability to override default touch input device hard-coded into LVGL.
The current default in the code is "/dev/input/event10" for whatever reason,
let user override this. Pick "/dev/input/touchscreen" as the OE default, as
that is more likely to be present on embedded hardware.
