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.

Does moving this call earlier in the function need to happen in patch
#13 rather than here?  That patch converts the internals of
i915_ggtt_probe_hw() to use to_gt()->ggtt, but I believe until this
patch that pointer is uninitialized.
