This patch bases on patch of Ulf Samuelsson
([PATCH 1/1] ARM: Add command to control coloured led from the console,
Wed Jan 7 21:09:55 CET 2009)
It allows any board implementing the user LED API
to control the LEDs from the console.

led [ 1 | 2 | 3 | 4 | 5 | all ]  [ on | off ]

Adding configuration item CONFIG_CMD_LED enables the command.
The items CONFIG_LED1...5 configure the associated gpio-pins.
