We need to block DC6 entry in case of Panel Replay as enabling VBI doesn't
prevent DC6 in case of Panel Replay. This causes problems if user-space is
polling for vblank events.

  drm/i915/display: Add block_dc6_needed variable into intel_crtc
  drm/i915/display: Prevent DC6 while vblank is enabled for Panel Replay
