[U-Boot] [PATCH] AT91: Add support for blue_LED_* and add coloured_LED_init to at91/led.c

[Albin Tonnerre]

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.
