[PATCHv5 8/9] arm64: dts: imx8m: update spdif sound card node properties

[Elinor Montmasson <elinor.montmasson@xxxxxxxxxxxxxxxxxxxx>]

Following merge of imx-spdif driver into fsl-asoc-card:
* update properties to match those used by fsl-asoc-card.
* S/PDIF in/out dummy codecs must now be declared explicitly, add and
  use them.

These modifications were tested only on an imx8mn-evk board.
