drm/i915/audio: Track audio state per-transcoder

Browse source

The audio logic lives in the transcoder rather than the pipe,
so start tracking it like that.

This is only really important for bigjoiner cases where tracking
by pipe doesn't work at all since intel_audio_codec_{enable,disable}()
won't even be called for the slave pipe. This means the state
checker won't find the ELD for the slave pipe and gets upset.
The PD->has_audio readout does currently work since that gets
read out from the same transcoder for both pipes.

For other cases this doesn't actually matter since it's only
the normal pipe transcoders that are audio capable, whereas
the more special transcoders (EDP/DSI) are not.
