We have approximately two copies of pre_commit_crtc_state(), one in the DSB code, the other in the vblank evasion code. Combine them into one. The slight difference between the two is that vblank evasion doesn't have a full atomic state (when called from the legacy cursor code), so it gets the old and new crtc state passed in by hand.
