Nicholas Kazlauskas 6ce8f31667 drm/amd/display: Add drm_audio_component support to amdgpu_dm
[Why]
The drm_audio_component can be used to give pin ELD notifications
directly to the sound driver. This fixes audio endpoints disappearing
due to missing unsolicited notifications.

[How]
Send the notification via the audio component whenever we enable or
disable audio state on a stream. This matches what i915 does with
their drm_audio_component and what Takashi Iwai's proposed hack for
radeon/amdpgu did.

This is a bit delayed in when the notification actually occurs, however.
We wait until after all the programming is complete rather than sending
the notification mid sequence.

Particular care is needed for the get ELD callback since it can happen
outside the locking and fencing DRM does for atomic commits.
