    drm/i915: implement BSD ring buffer V2
    The BSD (bit stream decoder) ring is used for accessing the BSD engine
    which decodes video bitstream for H.264 and VC1 on G45+.  It is
    asynchronous with the render ring and has access to separate parts of
    the GPU from it, though the render cache is coherent between the two.
