It would be more in the modern style to write it with the child device
struct embedded in the parent struct, object_initialize_child() in the
parent init, and object_property_set_bool(..., true, "realized", ...)
in the parent realized, but I guess this fits with the way the
rest of the existing device is written.

Series applied to target-arm.next, thanks.
