sysbus: Convert qdev_set_parent_bus() use with Coccinelle, part 1

I'm converting from qdev_set_parent_bus()/realize to qdev_realize();
recent commit "qdev: Convert uses of qdev_set_parent_bus() with
Coccinelle" explains why.

sysbus_init_child_obj() is a wrapper around
object_initialize_child_with_props() and qdev_set_parent_bus().  It
passes no properties.

Convert sysbus_init_child_obj()/realize to object_initialize_child()/
qdev_realize().
