[PATCHv6 2/2] INPUT: Introduce generic trigger/LED pairs to input LEDs

I applied patches on top of 3.20-rc0. Note that capslock LED was broken _before_ this change
on both thinkpad and desktop, and that Numlock on thinkpad did crazy stuff _before_ this 
change, too.

In default configuration, everything works as before. (Good).

echo kbd-numlock > vt::capsl/trigger makes capslock led stay on after cycling the led
(on thinkpad). heartbeat trigger works.

echo heartbeat > input4::capsl/trigger has expected effect.

echo heartbeat > input4::numl/trigger does not seem to have any effect.

Ok, it seems that numlock is just being handled specially on thinkpad (it also means 
uio keys change meaning), I guess that's nothing to worry about.
