Hi,

Sean Anderson's recent patch series is introducing more read-write
operations on the MDIO bus that only need to happen if a change is
being made.

We have similar logic in __mdiobus_modify_changed(), but we didn't
add its correponding locked variant mdiobus_modify_changed() as we
had very few users. Now that we are getting more, let's add the
helper.
