net: phy: realtek: add support for RTL8126A-integrated 5Gbps PHY

A user reported that first consumer mainboards show up with a RTL8126A
5Gbps MAC/PHY. This adds support for the integrated PHY, which is also
available stand-alone. From a PHY driver perspective it's treated the
same as the 2.5Gbps PHY's, we just have to support the new PHY ID.
