drm/amd/display: move odm power optimization decision after subvp optimization

[why]
ODM power optimization excludes subvp power optimization but subvp
optimization can override ODM power optimization even if subvp optimization
configuration is not found. This happens with 4k144hz + 1 5k desktop plane.
We could have applied ODM power optimization however this is overridden by
subvp but subvp ends up deciding not apply its optimization.

[how]
Move ODM power optimization decision after subvp so it will try ODM power
optimization after subvp optimization is not possible.
