Theres still one catch at the moment, AFAIK in linux you can put the PHYs either in the mdio controller node or in a "mdio" subnode within the ethernet controller node. I'm not sure wether the latter works in u-boot, but [1] looks promising. At least, linux dtbs are using the mdio subnodes and u-boot put the phys into the mdio controller node.
Please change Linux for that, move the PHYs from the per-port MDIO node to the PF 3 central MDIO controller node. Due to hardware reasons, the per-port MDIO controller registers are in fact de-featured and should be hidden from new LS1028A reference manuals.
Care to share some more details? There should be some more information besides "for hardware reasons" which should go into the commit message. Is there an erratum?
In fact, I guess in Rev0 of the RM it has already been removed, at least from the port memory map (in the RevB RM it was still present).
