qdev: gpio: Re-implement qdev_connect_gpio QOM style
Re-implement as a link setter. This should allow the QOM framework to
keep track of ref counts properly etc.
We need to add a default parent for the connecting input incase it's
coming from a non-qdev source. We simply parent the IRQ to the machine
in this case.
