commit d58f0083d39a17f8e5efbef522f822625956477e (HEAD -> drm-intel-next-queued, drm-intel/for-linux-next, drm-intel/drm-intel-next-queued)

    drm/i915/selftests: Mark the whole mock device as DMA capable
    
    Being a mock device, we suffer no DMA restrictions, so set the coherent
    mask to 64b.
    
    v2: Fix up mock_huge_selftests
