Probably we should drop SGMII_2500 from this series, introduce "manage" devicetree property(that would indicate if inband supported or not).
For example this is armada-8040-mcbin.dtsi In kernel, when in-band supported:
&cp1_eth2 {
	/* CPS Lane 5 */
	status = "okay";
	/* Network PHY */
	phy-mode = "2500base-x";
	managed = "in-band-status";
	/* Generic PHY, providing serdes lanes */
	phys = <&cp1_comphy5 2>;
	sfp = <&sfp_eth3>;

If in-band not supported(for example PPv2 MAC connected to 88E2110 in 2.5G speed) we would use default managed = "auto" and fixed link property.
