[U-Boot] [PATCH] cmd/led: check subcommand "list" instead "l"

[Heiko Schocher]

current implementation for checking if "led list"
command is called checks only if "l" is passed to the
led command. This prevents switching leds with name
which starts also with a "l". So check for passing
"list".

While at it, also fix a typo in led command usage.
