net: dsa: Fix functional dsa-loop dependency on FIXED_PHY

[ Upstream commit 40013ff20b1beed31184935fc0aea6a859d4d4ef ]

We have a functional dependency on the FIXED_PHY MDIO bus because we register
fixed PHY devices "the old way" which only works if the code that does this has
had a chance to run before the fixed MDIO bus is probed. Make sure we account
for that and have dsa_loop_bdinfo.o be either built-in or modular depending on
whether CONFIG_FIXED_PHY reflects that too.
