    gpio/rockchip: fix refcount leak in rockchip_gpiolib_register()
    
    [ Upstream commit 63ff545af73f759d1bd04198af8ed8577fb739fc ]
    
    The node returned by of_get_parent() with refcount incremented,
    of_node_put() needs be called when finish using it. So add it in the
    end of of_pinctrl_get().
