hw/arm/fsl-imx6: Fix introspection problems with the "fsl, imx6" device
Running QEMU with valgrind indicates a problem here: echo "{'execute':'qmp_capabilities'} {'execute':'device-list-properties'," \ "'arguments':{'typename':'fsl,imx6'}}" \ "{'execute': 'human-monitor-command', " \ "'arguments': {'command-line': 'info qtree'}}" | \ valgrind -q aarch64-softmmu/qemu-system-aarch64 -M none,accel=qtest -qmp stdio [...] ==32417== Invalid read of size 8 ==32417== at 0x618A7A: qdev_print (qdev-monitor.c:686) ==32417== by 0x618A7A: qbus_print (qdev-monitor.c:719) ==32417== by 0x452B38: handle_hmp_command (monitor.c:3446) [...] Use the new sysbus_init_child_obj() and object_initialize_child() to make sure that the objects are removed correctly when the parent gets destroyed.
