GGTT is currently available both through i915->ggtt and gt->ggtt, and we
eventually want to get rid of the i915->ggtt one.
Use to_gt() for all i915->ggtt accesses to help with the future
refactoring.

I think we can also convert the two references in i915_drm_suspend() and
i915_drm_resume(), right?  With those converted, I think the only
remaining use of i915->ggtt will be the call to intel_gt_init_hw_early()
during startup that assigns the gt->ggtt pointer.  Maybe we should just
make that function assign a drmm_kzalloc() and drop the i915->ggtt
completely?
