Subject: [PATCH net-next] net: mdio: Remove of_phy_attach()

We have no in-tree users, also update the sfp-phylink.rst documentation
to indicate that phy_attach_direct() is used instead of of_phy_attach().

    For the most part, ``flags`` can be zero; these flags are passed to
-   the of_phy_attach() inside this function call if a PHY is specified
+   the phy_attach_direct() inside this function call if a PHY is specified
    in the DT node ``node``.
 
    ``node`` should be the DT node which contains the network phy property,
