Next commits, 8/9 and 9/9, update all DTS files that currently use
the "fsl,imx-audio-spdif" compatible.

For the next version I will state in this commit message the upcoming modifications to DTS
and compatibility, why it will be done, and that support for existing DTS is not dropped.
Previous `imx-spdif` driver used the dummy codec instead of
using declared spdif codecs. It was discussed in previous version of this contribution
that using the dummy codec isn't good practice. So one to one backward compatibility
isn't really possible.

Next commits, 8/9 and 9/9, update all DTS files that currently use
the "fsl,imx-audio-spdif" compatible.
From the users point of view, currently configured spdif audio cards
will behave just the same.
