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

[Armin Wolf <W_Armin@gmx.de>]

Since commit 8e04e5382aa9 ("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.

Fixes: d1c0c8996977 ("platform/x86: uniwill-laptop: Implement rainbow animation as trigger")
