The S/PDIF audio card support with compatible "fsl,imx-audio-spdif"
was merged from imx-spdif into the fsl-asoc-card driver.
It makes possible to use an S/PDIF with an ASRC.
This merge introduces new DT bindings to use with compatible
"fsl,imx-audio-spdif" to follow the way fsl-asoc-card works:
* the "spdif-controller" property from imx-spdif is named "audio-cpu"
in fsl-asoc-card.
* fsl-asoc-card uses codecs explicitly declared in DT
with "audio-codec".
With an SPDIF, codec drivers spdif_transmitter and
spdif_receiver should be used.
Driver imx-spdif used instead the dummy codec and a pair of
boolean properties, "spdif-in" and "spdif-out".
In an upcoming commit, in-tree DTs will be modified to follow these new
properties:
* Property "spdif-controller" will be renamed "audio-cpu".
* spdif_transmitter and spdif_receiver nodes will be declared
and linked to the fsl-asoc-card node with the property "audio-codec".
To keep backward compatibility with other DTs, support for
"spdif-controller", "spdif-in" and "spdif-out" properties is kept.
However, it is recommended to use the new properties if possible.
It is better to declare transmitter and/or receiver
in DT than using the dummy codec.
DTs using compatible "fsl,imx-audio-spdif" are still supported, and
fsl-asoc-card will behave the same as imx-spdif for these DTs.

Convert the fsl-asoc-card binding to YAML.
When testing dtbs_check, found below compatible strings
are not listed in document:
fsl,imx-sgtl5000
fsl,imx53-cpuvo-sgtl5000
fsl,imx51-babbage-sgtl5000

So add them in yaml file to pass the test.
Also correct the 'dai-format' to 'format' in document.
For 'audio-routing', the items are not listed. Because
this fsl-asoc-card is generic driver, which supports several
codecs, if list all the items, there will be a long list.
