pinctrl: renesas: rzt2h: Fix device node leak in rzt2h_gpio_register()

When calling of_parse_phandle_with_fixed_args(), the caller is
responsible for calling of_node_put() to release the device node
reference.

In rzt2h_gpio_register(), the driver fails to call of_node_put() to
release the reference in of_args.np, which causes a memory leak.

Add the missing of_node_put() call to fix the leak.
