ODM power optimization is only supported with single stream. When ODM power optimization is enabled, we might not have enough free pipes for enabling other stream.

2023-08-30drm/amd/display: update blank state on ODM changesWenjing Liu
When we are dynamically adding new ODM slices, we didn't update blank state, if the pipe used by new ODM slice is previously blanked, we will continue outputting blank pixel data on that slice causing right half of the screen showing blank image.

This could potentially cause hw and sw state synchronization issues and it is not permitted by dc commit design.
