Subject: [PATCH 1/2] ASoC: dt-bindings: fsl,audmix: Add support for i.MX952 platform

The specific feature for AUDMIX on i.MX952 is that it can be bypassed,
so add fsl,amix-bypass property for this feature, besides this there is
no power domain defined on i.MX952, so make power-domains to be
dedicated to i.MX8QM.
