drm/amd/display: Add KUnit tests for amdgpu_dm_audio

Browse source

Add KUnit tests for amdgpu_dm_audio.c.

Tests cover:
- amdgpu_dm_audio_init(): early exit when audio is disabled
- amdgpu_dm_audio_fini(): early exit when audio is not enabled
- fill_audio_info(): manufacturer and product ID propagation,
  display name copy, speaker allocation flags, CEA revision
  gating of audio mode copying (including the zero-mode case),
  and latency field propagation
- amdgpu_dm_audio_component_bind()/unbind(): component ops, device,
  and audio_component pointer are wired up on bind and cleared on
  unbind
- amdgpu_dm_audio_eld_notify(): callback is forwarded with the
  correct port and audio pointer, and the no-op guard paths for a
  missing component, audio_ops, or pin_eld_notify callback
