Re: [PATCH net-next v2 06/13] net: dsa: realtek: use phy_read in ds->ops

The ds->ops->phy_read will only be used if the ds->slave_mii_bus
was not initialized. Calling realtek_smi_setup_mdio will create a
ds->slave_mii_bus, making ds->ops->phy_read dormant.

Using ds->ops->phy_read will allow switches connected through non-SMI
interfaces (like mdio) to let ds allocate slave_mii_bus and reuse the
same code.
