Remove these assignment all at once. For the details one may look into the of_gpio_dev_init() implementation. While at it, remove duplicate parent device assignment where it is the case.

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.
