gpio: Get rid of legacy header
A bunch of core gpiolib files still include the <linux/gpio.h> legacy API header for no good reason. After this only the gpiolib-legacy.c file includes it, which is fine. The sysfs ABI code has a pointless wrapper function around gpio_to_desc() we can just loose. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
