[PATCH v3 3/6] gpio: max77620: Don't set of_node

The gpiochip_add_data() takes care of setting the of_node to the parent's
device of_node, hence there is no need to do it manually in the driver's
code. This patch corrects the parent's device pointer and removes the
unnecessary setting of the of_node.
