platform/x86: uniwill-laptop: Implement .hw_offloaded trigger callback

Browse Source 
Since commit 8e04e5382a ("leds: trigger: Add hw_offloaded() callback
and provide trigger_may_offload_to_hw attribute") the LED subsystem
allows triggers to report if they are being offloaded to the underlying
hardware. Implement the necessary callback so that the LED subsystem
knows that the lightbar trigger is always offloaded to hardware.
