drm/i915: Pass atomic state to intel_audio_codec_enable, v2.
drm_select_eld requires mode_config.mutex and connection_mutex
because it looks at the connector list and at the legacy encoders.
This is not required, because when we call audio_codec_enable we know
which connector it was called for, so pass the state.
This also removes having to look at crtc->config.
Changes since v1:
- Use intel_crtc->pipe instead of drm_crtc_index. (Ville)
