If we're using gpio-mmio with a pinctrl backend the direction callbacks need to finalize their work by calling into the pin control back-end. As I was made aware that the vf610 driver was missing only that to use gpio-mmio instead of custom code, I took a stab at it. This patch is made on top of Johan Korsnes bug fix, so it needs to be applied after that is in, if this works. Plese try it out on vf610!
