thermal: max77620: fix pinmux conflict on reprobe
Use the new helper for reusing a device-tree node of another device instead of managing the node references explicitly. This also makes sure that the new of_node_reuse flag is set if the device is ever reprobed, something which specifically now avoids driver core from attempting to claim any pinmux resources already claimed by the parent device.
