Subject: [PATCH net] net: dsa: loop: Add module soft dependency

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.

Fixes: 98cd1552ea27 ("net: dsa: Mock-up driver")
