drm/amd/display: Optimize bandwidth on following fast update
[Why] The current call to optimize_bandwidth never occurs because flip is always pending from the FULL and FAST updates. [How] Optimize on the following flip when it's a FAST update and we know we aren't going to be modifying the clocks again.
