This disables LEDs that have a trigger function assigned right before
the trigger is installed. As the trigger was parsed before the LED has
been registered, also swap LED registration and trigger parsing.

a LED no set function will be there. Fail gracefully in this
case.

The FSF address has changed in the past. Instead of updating it
each time the address changes, just drop it completely treewide.

The LED core itself does not need gpio support, so remove include
so that it compiles on architectures without gpio support.
