[ Upstream commit f40a673d6b4a128fe95dd9b8c3ed02da50a6a862 ]

In an upcoming change, mdio_bus_phy_may_suspend() will need to
distinguish a phylib-based PHY client from a phylink PHY client.
For that, it will need to compare the phydev->phy_link_change() function
pointer with the eponymous phy_link_change() provided by phylib.

To avoid forward function declarations, the default PHY link state
change method should be moved upwards. There is no functional change
associated with this patch, it is only to reduce the noise from a real
bug fix.
