Adds a Kconfig option LV_Z_POINTER_FROM_CHOSEN_TOUCH which automatically creates a lvgl input pointer device from the chosen zephyr,touch node. Signed-off-by: Fabian Blatz <fabianblatz@gmail.com>
With the new LV_Z_POINTER_FROM_CHOSEN_TOUCH most boards do not need to specify a dedicated pseudo device anymore. Signed-off-by: Fabian Blatz <fabianblatz@gmail.com>
After removing the `zephyr,lvgl-pointer-input` device the init level entries have shifted by one entry. Update them accordingly. Signed-off-by: Fabian Blatz <fabianblatz@gmail.com>
Add explanation of the `CONFIG_LV_Z_POINTER_FROM_CHOSEN_TOUCH` interaction with the `zephyr,touch` chosen node. Signed-off-by: Fabian Blatz <fabianblatz@gmail.com>

Having the need to add a pseudo input device for LVGL in every board that has a touch controller onboard is unfortunate.
Instead create a pointer input device for boards where the
zephyr,touchnode is present. Move any modifications to the pointer withinvert-x,yetc. into the touch controller itsself, so other non LVGL samples also benefit from the corrected coordinate reporting behaviour.
