Auger Eric April 28, 2015, 4:51 p.m. UTC 
qdev_init_gpio_out_named takes a new argument corresponding to the
check callback passed to object_property_add_link. In qdev_init_gpio_out
and sysbus_init_irq, this callback is currently set to the dummy
object_property_allow_set_link.

This will allow qdev_init_gpio_out_named callers to specialize this
callback. A subsequent patch will implement that for sysbus.
