In the ARMv5 allmodconfig build, this fails because CONFIG_PHY=m, and
we can't call into it. You could use IS_BUILTIN instead of IS_ENABLED in
the header as a oneline workaround, but I think that would be more confusing
to real users that try to use CONFIG_PHY=m without realizing why they lose
access to their switch.
