led: triggers: Add LED_INIT_DEFAULT_TRIGGER flag
Add the flag LED_INIT_DEFAULT_TRIGGER for indicating that trigger being set is a default trigger for the LED class device, and thus it should be initialized with settings provided in the fwnode. Set the flag in the led_trigger_set_default(). It is expected to be cleared in the activate() op of a trigger after trigger fwnode initialization data is parsed and applied. This should happen only once after LED class device registration, to allow leaving triggers in the idle state on re-apply and let the users apply their own settings without interference from the default ones.
