drm/i915/psr: Use TRANS_PUSH to trigger frame change event

Now we have everything in place for triggering PSR "frame change" event
using TRANS_PUSH: use TRANS_PUSH for LunarLake and onwards.

v4:
  - Added call to intel_vrr_psr_frame_change_enable call
  - added setting LNL_TRANS_PUSH_PSR_PR_EN into intel_vrr_send_push
v3: use HAS_PSR_FRAME_CHANGE macro
v2: use AND instead of OR in intel_psr_use_trans_push
