drm/i915: announce to userspace that the bsd ring is coherent
Otherwise we can't really fix the abi-braindeadness of forcing
libva to manually wait for rendering when switching rings. Which
in turn makes implementing hw semaphores a pointless exercise
(at least for ironlake).
[Also added the relaxed fencing param to explain the jump in
numbering - relaxed fencing is in -next.]
