[Qemu-devel] [PATCH v2 1/4] arm: remove remaining cannot_destroy_with_object_finalize_yet

[Laurent Vivier <lvivier@redhat.com>]

With commit ce5b1bbf624b ("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).
