hwmon: (gpio-fan) Mandate OF_GPIO and cut pdata path
We have no users of platform data, we made platform data driver-local, so cut all #ifdefs for the platform data case, and depend on the Kconfig CONFIG_OF_GPIO symbol. Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Guenter Roeck <linux@roeck-us.net>
