This will break existing users in counjuntion with the previous patch. Previously if the user provided platform data but left gpio_base as zero we'd use -1 and let gpiolib pick for us. Now instead the driver will take that zero and pass it on to gpiolib, probably failing as the SoC will have taken the low numbered GPIOs.
