Note that the pinctrl conversion also fixes GPIO support for ns2 boards.
Since commit f9e75922: "ARM: Kirkwood: Make use of mvebu pincltl and
gpio", the mvbu_gpio driver is used for DT boards. As mvbu_gpio relies
on the pinctrl driver, then a pinctrl definition must be given to allow
the GPIO configuration.
