Changes in v2:
- Add missing CODEC pin options to 'atmel,audio-routing' items.
- Drop 'minItems' from 'atmel,audio-routing' since enum defines valid connections.
- Add subsystem tag to subject.
- Add blank line between properties and fix typo.
- Add audio complex description.
- Link to v1: https://lore.kernel.org/lkml/20240214-at91sam9g20ek-wm8731-yaml-v1-1-33333e17383b@microchip.com
