Useful for: 1: Implementing lightweight devices that don't want to keep pointers to their own GPIOs. They can get their GPIO pointers at runtime from QOM using this API. 2: testing or debugging code which may wish to override the hardware generated value of of a GPIO with a user specified value (E.G. interrupt injection).
