In my configuration FIXED_PHY is selected by several other modules:
  │ Selected by [y]:
  │   - FSL_DPAA_ETH [=y] && NETDEVICES [=y] && ETHERNET [=y] &&
NET_VENDOR_FREESCALE [=y] && FSL_DPAA [=y] && FSL_FMAN [=y]
  │   - FWNODE_MDIO [=y] && NETDEVICES [=y] && MDIO_DEVICE [=y] &&
(ACPI [=y] || OF [=y] || COMPILE_TEST [=n])
  │   - OF_MDIO [=y] && NETDEVICES [=y] && MDIO_DEVICE [=y] && OF [=y]
&& PHYLIB [=y]

..so it looks pretty tied up with the MDIO support which I guess I
will need for the real PHY!

If I sorted out building the dsa_loop_bdinfo.c code as a built-in do
you think that would solve the ordering issue?
