drm/amd/display: Optimize bandwidth on following fast update
commit 34316c1e561db0b24e341029f04a5a5bead9a7bc upstream.
[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.
