drm/amd/display: always switch off ODM before committing more streams

Browse source

commit 49a30c3d1a upstream.

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. So when we are committing more than 1 stream we
should first switch off ODM power optimization to make room for new
stream and then allocating pipe resource for the new stream.
