Convert the lantiq,gswip bindings to YAML format. Also add this new file to the MAINTAINERS file. Furthermore, the CPU port has to specify a phy-mode and either a phy or a fixed-link. Since GSWIP is connected using a SoC internal protocol there's no PHY involved. Add phy-mode = "internal" and a fixed-link to the example code to describe the communication between the PMAC (Ethernet controller) and GSWIP switch.
