[scarthgap][RFC PATCH 0/3] Add pipeWire audio stack for am62dxx

This patch series introduces PipeWire audio support for AM62Dxx platform,
replacing PulseAudio with the modern PipeWire audio server architecture.

PipeWire is a modern audio/video server that provides low-latency, high-performance
audio processing with better resource management and flexible routing capabilities.
WirePlumber serves as the session manager, providing policy management and device
configuration for PipeWire, enabling automatic audio routing and device handling.

PipeWire offers several advantages over PulseAudio:
- Lower latency and better real-time performance.
- Unified handling of both audio and video streams.
- Better support for professional audio applications.
- Improved security model with per-client sandboxing.
- More efficient resource usage and power management.
- Native support for modern audio formats and sample rates.

The series includes:

Patch 1: Add PipeWire configuration files with capture and multichannel setup.

Patch 2: Add WirePlumber configuration with audio defaults service.

Patch 3: Enable PipeWire audio stack in tisdk-default-image for am62dxx.

This implementation provides a complete audio solution with ALSA and PulseAudio
compatibility layers, ensuring backward compatibility while leveraging PipeWire's
advanced capabilities.
