H A Di915_gem_mman.hcb2baf42 Thu Jul 02 11:36:22 CDT 2020 Chris Wilson <chris@chris-wilson.co.uk> drm/i915/gem: Only revoke the GGTT mmappings on aperture detiling changes

Only a GGTT mmapping will use the aperture detiling registers, so on a
tiling change for an object, we only need to revoke those mmappings and
not the CPU mmappings (which are always linear irrespective of the tiling).
