[PATCH 1/3] qdev: pass the check callback to qdev_init_gpio_out_named

[Eric Auger <eric.auger@linaro.org>]

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
this callback is set to the dummy object_property_allow_set_link.

This will allow qdev_init_gpio_out_named callers to specialize this
callback, typically sysbus.
