drm/amd/display: optimize bandwidth after commit streams.

Browse Source 
[Why]
System is unable to enter S0i3 due to DISPLAY_OFF_MASK not asserted
in SMU.

[How]
Optimized bandwidth should be called paired and to resolve unplug
display underflow issue, optimize bandwidth after commit streams is
moved to next page flip, in case of S0i3, there is a change for no
flip coming causing display count is 1 in SMU side.
Add optimize bandwidth after commit stream.
