net: dsa: Do not override PHY interface if already configured
In case we need to divert reads/writes using the slave MII bus, we may have already fetched a valid PHY interface property from Device Tree, and that mode is used by the PHY driver to make configuration decisions. If we could not fetch the "phy-mode" property, we will assign p->phy_interface to PHY_INTERFACE_MODE_NA, such that we can actually check for that condition as to whether or not we should override the interface value.
