cmd: led: fix help text for blink subcommand
The blink subcommand actually requires an additional parameter
(blink-freq) but not the others.
In order to simplify the help text, split the blink subcommand help text
from the off|on|toggle subcommands.
Then, fix the help text so that it is clear that the frequency is
required.
While at it, specify the duty cycle.
