intel_gt_init_hw_early is defined as

        void intel_gt_init_hw_early(struct intel_gt *gt, struct i915_ggtt *ggtt)
        {
                gt->ggtt = ggtt;
        }

so this call is now essentially doing

        to_gt(dev_priv)->ggtt = to_gt(dev_priv)->ggtt

which isn't what you intended.  It might be better to just drop the
function completely and instead assign the gt's ggtt pointer here to a
drmm_kzalloc() dynamic allocation.
