As we've agreed that using I915_GEM_PREAD/PWRITE IOCTLs on dma-buf objects doesn't make much sense, we are not going to extend their handlers in the i915 driver with new processing paths required for them to work correctly with dma-buf objects on future hardware with no mappable aperture. When running on that kind of hardware, just skip subtests which use those IOCTLs.
