Laurent Vivier 53d6e53189 arm: remove remaining cannot_destroy_with_object_finalize_yet
With commit ce5b1bbf62 ("exec: move cpu_exec_init() calls to
realize functions"), we can now remove all the
remaining cannot_destroy_with_object_finalize_yet as
unsafe references have been moved to cpu_exec_realizefn().
(tested with QOM command provided by commit 4c315c27).
