> Being part of the GT HW, it make sense to keep the guc/huc structures
> inside the GT structure. To help with the encapsulation work done by the
> following patches, both structures are placed inside a new intel_uc
> container. Although this results in code with ugly nested dereferences
> (i915->gt.uc.guc...), it saves us the extra work required in moving
> the structures twice (i915 -> gt -> uc). The following patches will
> reduce the number of places where we try to access the guc/huc
> structures directly from i915 and reduce the ugliness.
