Combine comments' from v2 and v3. I hope I address everythings.

- Krzysztof's comments
- add reson about why change

- rob's comments
using rob's suggest logic to restrict interrupt number
but for dma-names, still need use oneOf to cover 3 case
- [rx, tx]
- [rx]
- [tx]

- items:
- tx
- rx
- enums: [rx, tx]

- Conor's comments
- add power-domains required for imx8qxp and imx8qm
- remove dmas descript, not allow use index to get dma-channel. Current
no user using this method.

- Link to v3:

Changes in v3:
- Fixed dtschema/dtc warnings/errors:

from schema $id:,spdif.yaml#
