gpio: shared: assign the correct firmware node for reset-gpio use-case

Browse Source 
When we defer probe due to unlucky timing of adding the lookup table, we
assign the matching firmware node to the shared reference for the future
probing. However, the fwnode we assign is wrong so fix it and assign the
one associated with the reset-gpio device.
