Currently, at91/led.c only provides _on and _off functions for green, yellow and red LEDs. This patch provides a generic coloured_LED_init function, which is a first step towards getting rid of the board-specific (and duplicated) board/*/*/led.c files on at91 This patch alos adds similar support for blue LEDs, mostly for the sake of completeness.
