hw/core/resettable: add support for changing parent
Add a function resettable_change_parent() to do the required
plumbing when changing the parent a of Resettable object.
We need to make sure that the reset state of the object remains
coherent with the reset state of the new parent.
We make the 2 following hypothesis:
+ when an object is put in a parent under reset, the object goes in
reset.
+ when an object is removed from a parent under reset, the object
leaves reset.
The added function avoids any glitch if both old and new parent are
already in reset.
