[PATCH net 2/2] net: dsa: bcm_sf2: Utilize nested MDIO read/write

[Florian Fainelli <f.fainelli@gmail.com>]

We are implementing a MDIO bus which is behind another one, so use the
nested version of the accessors to get lockdep annotations correct.

Fixes: 461cd1b03e32 ("net: dsa: bcm_sf2: Register our slave MDIO bus")
