[U-Boot] [PATCH 1/1] at91: Add command to control up to 3 GPIO LEDs from the console

[Daniel Gorsulowski]

The folowing patch tries to fix all defects of the previous patch.
The new led command is _not_ limited to 3 LEDs any more, but it
is still restricted to at91 architectures.

Best regards,
Daniel Gorsulowski
