While I understand it was helpful for you, I am not entirely convinced that we should add it in Xen with no-use. The code is simple enough for anyone to re-implement it if needed.

Add dt_print_node_names() to print all nodes under a dt_device_node. dt_print_node_names() takes a dt_device_node type input and prints the node name of all the subsequent nodes. This is added for debugging purpose for device tree overlays.
