gpiolib: of: Use correct fwnode for DT-probed chips

The OF node store in chip->fwnode is used to explicitly override the FW
node for a GPIO chip. For chips that use the default FW node (i.e. that
of their parent device), this will be NULL and cause the chip not to be
fully registered.

Instead, use the GPIO device's FW node, which is set to either the node
of the parent device or the explicit override in chip->fwnode.
