[PATCH v3 1/4] ASoC: dt-bindings: fsl,audmix: Add support for i.MX952 platform

[Shengjiu Wang <shengjiu.wang@nxp.com>]

Add a compatible string for i.MX952 platform.

There is a power domain on i.MX952 for the mix system of AUDMIX.
But it is enabled by default, AUDMIX device don't need to enable it,
so make the power-domains to be optional on i.MX952, and be required on
i.MX8QM.
