hw/cpu/arm11mpcore: Fix introspection problem with 'arm11mpcore_priv' 

Valgrind reports an error here:

echo "{'execute':'qmp_capabilities'} {'execute':'device-list-properties'," \
 "'arguments':{'typename':'arm11mpcore_priv'}}" \
 "{'execute': 'human-monitor-command', " \
 "'arguments': {'command-line': 'info qtree'}}" | \
 valgrind -q aarch64-softmmu/qemu-system-aarch64 -M none,accel=qtest -qmp stdio

Use sysbus_init_child_obj() to fix it.
