====================
ds->user_mii_bus cleanup (part 1)

There are some drivers which assign ds->user_mii_bus when they
don't really need its specific functionality, aka non-OF based
dsa_user_phy_connect(). There was some confusion regarding the
fact that yes, this is why ds->user_mii_bus really exists, so
I've started a cleanup series which aims to eliminate the usage
of ds->user_mii_bus from drivers when there is nothing to gain
from it.

Today's drivers are lantiq_gswip, qca8k and bcm_sf2. The work is
not done here, but a "part 2" may or may not come, depending on
other priorities.

All patches were only compile-tested.
