Chris Wilson 69a48c1d28 drm/i915/execlists: Reduce barrier on context switch to a wmb() 
Having been forced to reduce Braswell back to using the aliasing ppgtt,
the coherency issue we previously observed cannot impact us. Reduce the
performance penalty imposed on all platforms from using the mfence to a
mere sfence.
