Get rid of the inflexible bigjoiner_linked_crtc pointer thing and just track things as a bitmask of pipes instead. We can also nuke the bigjoiner_slave boolean as the role of the pipe can be determined from its position in the bitmask. It might be possible to nuke the bigjoiner boolean as well if we make encoder.compute_config() do the bitmask assignment directly for the master pipe. But for now I left that alone so that encoer.compute_config() will just flag the state as needing bigjoiner, and the intel_atomic_check_bigjoiner() is still responsible for determining the bitmask. But that may have to change as the encoder may be in the best position to determine how exactly we should populate the bitmask. Most places that just looked at the single bigjoiner_linked_crtc now iterate over the whole bitmask, eliminating the singular slave pipe assumption.
