From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>

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.
