[PATCH v2 1/5] net: dsa: mv88e6xxx: introduce support for two chips using direct smi addressing

The 88e6250 (as well as 6220, 6071, 6070, 6020) do not support multi-chip (indirect) addressing. However, one can still have two of them on the same mdio bus, since the device only uses 16 of the 32 possible addresses, either addresses 0x00-0x0F or 0x10-0x1F depending on the ADDR4 pin at reset
