gpio: Setup parent device and get rid of unnecessary of_node assignment
Some of the drivers do not set parent device. This may lead to obstacles during debugging or understanding the device relations from the Linux point of view. Assign parent device for GPIO chips created by these drivers. While at it, let GPIO library to assign of_node from the parent device.
