leds: Kconfig cleanup
Browse files Browse the repository at this point in the history 
Remove the need for "depends on LEDS_CLASS" by wrapping the affected
config options in an if/endif block. Similar for "depends on LEDS_TRIGGERS".

LEDS_COBALT_RAQ still has a "depends on LEDS_CLASS=y" since it cannot
be selected to build as a module.
