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.
