phy: micrel: Fix finding PHY properties in MAC node for KSZ9031.
commit b4c19f71252e3b6b8c6478fd712c592f00b11438 upstream.
Commit 651df2183543 ("phy: micrel: Fix finding PHY properties in MAC
node.") only fixes finding PHY properties in MAC node for KSZ9021. This
commit applies the same fix for KSZ9031.
Fixes: 8b63ec1837fa ("phylib: Make PHYs children of their MDIO bus, not the bus' parent.")
