[PATCH v6 1/4] ASoC: dt-bindings: fsl,imx-asrc/spdif: Add power-domains property

[Frank Li <Frank.Li@xxxxxxx>]

Add power-domains property for asrc and spdif since fsl,imx8qm-asrc/spdif
and fsl,imx8qxp-asrc/spdif require 'power-domains'.

Set 'power-domains' as required property for compatible string
fsl,imx8qm-asrc/spdif and fsl,imx8qxp-asrc/spdif.
