[media] media: Move media graph state for streamon/off to the pipeline
The struct media_entity_graph was allocated in the stack, limiting the number of entities that could be reasonably allocated. Instead, move the struct to struct media_pipeline which is typically allocated using kmalloc() instead. The intent is to keep the enumeration around for later use for the duration of the streaming. As streaming is eventually stopped, an unfortunate memory allocation failure would prevent stopping the streaming. As no memory will need to be allocated, the problem is avoided altogether.
