Removes the pseudo device prerequisite that the LVGL setup routine has been executed before initialization. The pseudo devices are now registered at the end of the LVGL setup routine, the driver is not concerned with configuring the devices anymore. This also removes the need for enforcing certain priorities within the same init level. This resolves issue #62753. Signed-off-by: Fabian Blatz <fabianblatz@gmail.com>
