Subject: net: dsa: bcm_sf2: Utilize nested MDIO read/write

From: Florian Fainelli <[email protected]>

[ Upstream commit 2cfe8f8290bd28cf1ee67db914a6e76cf8e6437b ]

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