sna/gen7: Request secure batches for Haswell vsync
Since commit 8ff8eb2b38dc705f5c86f524c1cd74a811a7b04c
Author: Chris Wilson <chris@chris-wilson.co.uk>

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.
