media: Documentation: mc: Replace deprecated graph walk API

2024-08-24T22:42:01+00:00

The graph walk API has been deprecated in commit eac564de0915 ("media: mc: entity: Add entity iterator for media_pipeline") in favour of pipelien iterators, but the MC documentation hasn't been updated accordingly. It still documents the deprecated API as the only option. Fix it by dropping the deprecated function, and documenting the new API.
