gpio: Fix build warnings on undefined struct pinctrl_dev

This fixes the warnings: * include/linux/gpio.h:254:11: warning: 'struct pinctrl_dev' declared inside parameter list will not be visible outside of this definition or declaration * include/linux/gpio/driver.h:602:11: warning: 'struct pinctrl_dev' declared inside parameter list will not be visible outside of this definition or declaration Fixes: 78b9957 ("pinctrl: remove unused pin_is_valid()") Reported-by: kbuild test robot <lkp@intel.com> Signed-off-by: Enrico Weigelt <info@metux.net> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
