drm/amd/display: Don't adjust VRR unnecessarily
[why] Do not need to spend time reprogramming DRR if there were no updates to the parameters. [how] Compare the current stream state to the requested one to determine if an update is required. In amdgpu_dm the timing_changed flag is set but never used so can remove it. Similarly, the stream update for VRR is done after dc_commit and should not update its adjust field until after the update is completed. The adjust field is managed by dc_stream_adjust_vmin_vmax and should not be manually updated in amdgpu_dm.
