[U-Boot] [PATCH] gpio: dwapb_gpio: fix broken dev->node

[Simon Goldschmidt]

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.

Fixes: commit 1b898ff ("gpio: dwapb_gpio: convert to livetree")

This applies on top of 0aec330931c5 in u-boot-socfpga/master which it
should be squashed into.
