leds: add flag to keep trigger always

Commit 0013b23d66a2768f5babbb0ea9f03ab067a990d8 ("leds: disable
triggers on brightness set") removes the trigger on a LED class
device when brightness is set to 0. However, there are some LED
class devices which needs the trigger not to be removed. In an
use case like camera flash, camera flash driver passes in a
trigger device to LED class driver. If the trigger is removed
when the brightness is set to 0, this will affect the clients
using those triggers. Hence add a flag to always keep the trigger
even when brightness is set to 0.
