sh: pfc: attach software node to the GPIO chip
With commit e5d527be7e69 ("gpio: swnode: don't use the swnode's name as
the key for GPIO lookup") gpiolib requires that firmware nodes from the
GPIO references to match firmware node in gpiochip structure.
Define a software node for the pfc gpiochip so that it can be referenced
by boards using static device properties.
