qdev: gpio: Register GPIO outputs as QOM links
Within the object that contains the GPIO output. This allows for
connecting GPIO outputs via setting of a Link property.
Also clear the link value to zero. This catch-alls the case
where a device improperly inits a gpio_out (malloc instead of
malloc0).
