drm/i915: Remove unused dev_priv->vblank_pipe

vblank_pipe was intended to be used for tracking DRI1 state. However, the vblank_pipe reported to DRI1 is fixed to umask both pipes, and the dev_priv->vblank_pipe unused and superfluous. Signed-off-by: Chris Wilson <[email protected]> Signed-off-by: Daniel Vetter <[email protected]>
