Wenjing Liu c51d87202d drm/amd/display: do not attempt ODM power optimization if minimal transition doesn't exist
[why]
In some cases such as 8k desktop surface with 144Hz timing, we decide to
enable ODM power optimization but this surface doesn't have a minimum
transition state. Therefore we cannot switch off ODM power optimization seamlessly
This creates path depedency on ODM power optimization decision. i.e
whether or not we should switch off ODM power optimization is dependent
on if the transition to switch off ODM power optimization from current state
is seamless. We don't desire a path dependent power optimization policy
as it is too dynamic and difficult to maintain.

[how]
Attempt ODM power optimization only after we can validate new state without
using pipe combine.
