Make GPIOF_ defined values available even when GPIOLIB nor GENERIC_GPIO is enabled by moving them to <linux/gpio.h>.

Looks good.
We probably may also want to move definition of struct gpio into include/linux/gpio.h to make things like this work as well:
static struct gpio some_gpios[] = { { GPIO_BLAH, GPIOF_IN, "BLAH"}, { GPIO_BLAH2, GPIOF_OUT_INIT_LOW, "BLAH2"}, };
static int some_init_function(void) { /* ... */
gpio_request_array(some_gpios, ARRAY_SIZE(some_gpios));
/* ... */ }
These gpio_request_one() and gpio_request_array() are quite handy, so I suppose more and more drivers will use it as we go...
