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.
