commit 1b898ff ("gpio: dwapb_gpio: convert to livetree") introduced a bug in that dev->node of the gpio chip was accidentally set to the of_node of its bank subnode.
What it meant to do was assign subdev->node, not dev->node.
While this doesn't affect too many use cases, iterating over the gpio chip's properties doesn't work any more after that, so fix this properly by calling 'device_bind_ofnode()' to bind the sub-device instead of calling 'device_bind()' and then assigning subdev->node manually.
