drm/i915: Mark up GTT sizes as u64

commit c58281056a8b26d5d9dc15c19859a7880835ef44 upstream.

Since we use a 64b virtual GTT irrespective of the system, we want to
ensure that the GTT computations remains 64b even on 32b systems,
including treatment of huge virtual pages.

No code generation changes on 64b:
