[PATCH] Add triggers for cubietruck leds

[Henry Paulissen <draakje197-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>]

This (small) patch gives the same led trigger functionality
as the 3.4 sunxi kernel and although mainline doesn't has
to be the same, it helps in identifying and builds upon the
user expectations about what those leds mean.
