drm/amd/display: add new windowed mpo odm minimal transition sequence

Browse source

[why]
We do not have a programming sequence to support seamless transition
between MPC combine to ODM combine when plane count remains the same.
This can happen with windowed MPO ODM use cases when plane scaling
is changed over ODM Combine's capability.

[How]
We are adding a programming sequence specifically to handle the transition
between MPC combine and ODM combine during plane scaling change.
