hw/arm/xlnx-zynqmp: Fix crash when introspecting the "xlnx, zynqmp" device
QEMU currently crashes when e.g. doing something like this:
echo "{'execute':'qmp_capabilities'} {'execute':'device-list-properties'," \
"'arguments':{'typename':'xlnx,zynqmp'}}" \
"{'execute': 'human-monitor-command', " \
"'arguments': {'command-line': 'info qtree'}}" \
| aarch64-softmmu/qemu-system-aarch64 -M none,accel=qtest -qmp stdio
Use the new object_initialize_child() and sysbus_init_child_obj()
functions to get the refernce counting of the child objects right, so
that they are properly cleaned up when the parent gets destroyed.
