drm/i915: Pass idle crtc_state to intel_dp_sink_crc

Browse Source 
IPS can only be enabled if the primary plane is visible, so
first make sure sw state matches hw state by waiting for hw_done.

After this pass crtc_state to intel_dp_sink_crc() so that can be used,
instead of using legacy pointers.
