net: phy: motorcomm: Add a dedicated .config_init for YT8531S

The YT8531S PHY configuration logic is similar to the YT8521, but with
some extra steps for the RGMII configuration. In preparation for
improvements in the YT8531S configuration for the version found
integrated with the YT6801 PCIe NIC, let's split the logic out by
extending the YT8521 configuration sequence.
