Exporting the symbols like intel_gtt_* creates some confusion inside
i915 that has symbols named similarly. In an attempt to isolate
platforms needing intel-gtt.ko, commit 7a5c922377 ("drm/i915/gt: Split
intel-gtt functions by arch") moved way too much
inside gt/intel_gt_gmch.c, even the functions that don't callout to this
module. Rename the symbols to make the separation clear.
