Currently the board file for Nokia 770 creates dummy software nodes not attached in any way to the actual GPIO controller devices and uses the fact that GPIOLIB matching swnode's name to the GPIO chip's label during software node lookup. This behavior is wrong and we want to remove it. To that end, we need to first convert all existing users to creating actual fwnode links. Create real software nodes for GPIO controllers on OMAP16xx and reference them from the software nodes in the nokia board file.
