net: dsa: loop: Add module soft dependency

[ Upstream commit 3047211ca11bf77b3ecbce045c0aa544d934b945 ]

There is a soft dependency against dsa_loop_bdinfo.ko which sets up the
MDIO device registration, since there are no symbols referenced by
dsa_loop.ko, there is no automatic loading of dsa_loop_bdinfo.ko which
is needed.
