hw/misc/led: Allow connecting from GPIO output
Some devices expose GPIO lines. Add a GPIO qdev input to our LED device, so we can connect a GPIO output using qdev_connect_gpio_out(). When used with GPIOs, the intensity can only be either minium or maximum. This depends of the polarity of the GPIO (which can be inverted). Declare the GpioPolarity type to model the polarity.
