Chris Wilson cbc1f3cb67 drm/i915: Skip CPU synchronisation on dmabuf attachments
dma-bufs are device coherent, with explicit CPU synchronisation provided
via the begin/end cpu access ioctls. As the coherency of the dma-buf is
explicitly defined to be under user control, flushing any caches on
attach/detach of the dma-buf is additional work that doesn't aide the
user in the slightest.
