When trying to add a gpio-hog, we enter a weird loop where the gpio-ranges is needed when gpiochip_add_data() is called but in the current implementation the ranges are added from the driver afterwards.
A simple solution is to rely on the DR gpio-ranges attribute and remove the call to gpiochip_add_pin_range().
