add generic stubs for GPIO LEDs
For boards that support LEDs driven via GPIO (CONFIG_GPIO_LED), it may be useful to have some generic stubs (wrapper functions) for the "colored" LEDs. This allows defining STATUS_LED_* values directly to GPIO numbers, e.g.: #define STATUS_LED_GREEN 248 /* = PH24 */ To keep those optional, it's probably best to introduce an additional configuration setting. I've chosen CONFIG_GPIO_LED_STUBS for that. Placing the code in drivers/misc/gpio_led.c also ensures that it automatically depends on CONFIG_GPIO_LED too.
