The function qdev_init_gpio_in_named() passes the DeviceState pointer
as the opaque data pointor for the irq handler function. Usually
this is what you want, but in some cases it would be helpful to use
some other data pointer.
Add a new function qdev_init_gpio_in_named_with_opaque() which allows
the caller to specify the data pointer they want.
