We want to convert the legacy gpio-keys platform device on BCM47XX
boards to use software nodes. To do this properly and allow
referencing the GPIO controller by address rather than relying on
name-based matching (which is being removed from the gpiolib core),
we need to associate the GPIO controller with a software node.

Introduce ssb_gpio_swnode, register it, and associate it with the
gpio_chip.
