Ansuel Smith a4604b3cde net: dsa: qca8k: fix kernel panic with legacy mdio mapping ...

[ Upstream commit ce062a0adb ]

When the mdio legacy mapping is used the mii_bus priv registered by DSA
refer to the dsa switch struct instead of the qca8k_priv struct and
causes a kernel panic. Create dedicated function when the internal
dedicated mdio driver is used to properly handle the 2 different
implementation.
