hw/cpu/a9mpcore: Fix introspection problems with the "a9mpcore_priv" device
Running QEMU with valgrind indicates a problem here:
echo "{'execute':'qmp_capabilities'} {'execute':'device-list-properties'," \
"'arguments':{'typename':'a9mpcore_priv'}}" \
"{'execute': 'human-monitor-command', " \
"'arguments': {'command-line': 'info qtree'}}" | \
valgrind -q aarch64-softmmu/qemu-system-aarch64 -M none,accel=qtest -qmp stdio
[...]

Use the new sysbus_init_child_obj() function to make sure that the objects
are cleaned up correctly when the parent gets destroyed.
