Currently, U-Boot doesn't parse a "max-speed" DT property in a phy's DT node. That property is a standard binding which should be honoured, and in linux that is done by the core phy code via a call to an of_set_phy_supported() helper. (Some ethernet drivers support a max-speed property in their DT node, but that's orthogonal to what the phy supports.)
Add a similar helper in U-Boot, and call it from phy_config().
