sysbus: New sysbus_realize(), sysbus_realize_and_unref()
Sysbus devices almost always plug into the main system bus.
qdev_create() even has a convenience feature to make that easy: a null
bus argument gets replaced by the main system bus. qdev_realize() and
qdev_realize_and_unref() do the same.
We can do better. Provide convenience wrappers around qdev_realize()
and qdev_realize_and_unref() that don't take a @bus argument. They
always pass the main system bus.
