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.

v3: check that encoder is dp
v2: set/clear block_dc6_needed in intel_crtc_vblank_on/off

Jouni Högander (2):
  drm/i915/display: Add block_dc6_needed variable into intel_crtc
  drm/i915/display: Prevent DC6 while vblank is enabled for Panel Replay
