From: Bartosz Golaszewski <redacted> Describe the firmware-managed variant of the QCom DesignWare MAC. As the properties here differ a lot from the HLOS-managed variant, lets put it in a separate file. Since we need to update the maximum number of power domains, let's update existing bindings referencing the top-level snps,dwmac.yaml and limit their maxItems for power-domains to 1.
