Subject[PATCH] leds-class: change back LEDS_CLASS to tristate instead of bool
Date
LEDS_CLASS is required by leds and trigger drivers, but we can build it as
module. So change this option back as tristate and treak the help message
as well.

LEDS_TRIGGERS depends on LEDS_CLASSS, which should be tristate. So set it
as tristate too and update header files as well.

Change those ifdefs to take care of module configuration.
