platform/x86: gpd pocket fan: Clean-up by using managed work init
Few drivers implement remove call-back only for ensuring a delayed work gets cancelled prior driver removal. Clean-up these by switching to use devm_delayed_work_autocancel() instead. This change is compile-tested only. All testing is appreciated.
