If use of_platform_populate to scan dt-nodes and add devices, the subnode of root(such as /smmu), when being scanned and invoke of_device_add, the ofdev->dev.parent is always equal &platform_bus. So that, function set_dev_node will not be called. And in device_add, dev_to_node(parent) always return NUMA_NO_NODE.
