Implemented the Contiki leds driver
NB! This is by no means a future-proof implementation. However, it should be a good starting point. Configuration of the LEDS_ARCH_* defines in the leds-arch.c file is what determines what LEDs are available of a given device/target. This information should be sufficient from the Board file/device name, and can from there hardcod what board+device combination a given LED should support.
