    sna/gen7: Request secure batches for Haswell vsync

        sna/hsw: Scanline waits require both DERRMR and forcewake
    
    we have been emitting LRI to enable vsync on the render ring. This
    requires a privileged batch buffer, and whilst we were checking for
    kernel support, we forgot to actually tell the kernel to submit the
    batch with the right privileges.
