Subject: [PATCH 0/3] Update DC commit sequence

This patchset introduces the basic infrastructure to change our display commit sequence to make it more robust and flexible for handling some display features. Current, amdgpu_dm tries to commit a validation state directly into update_planes and commit_streams. However, we want to avoid committing the state directly into DC; instead, we only want to pass streams/plane pointers into DC and let it manage the commit state entirely. This behavior is more future-proof because it keeps the state manipulation inside DC, which can benefit some specific features that might want to play with the context state.
