[PATCH 7/7] drm/i915/display: Generate PSR frame change event on cursor update

[Jouni Högander]

On LunarLake and onwards we are using vrr send push mechanism to trigger
frame change event. Due to this we need to trigger it using
intel_vrr_psr_send_push provided by VRR code on legacy cursor update.
