phy: provide a hook for link up/link down events
Sometimes, we need to do additional work between the PHY coming up and
marking the carrier present - for example, we may need to wait for the
PHY to MAC link to finish negotiation. This changes phylib to provide
a notification function pointer which avoids the built-in
netif_carrier_on() and netif_carrier_off() functions.
Standard ->adjust_link functionality is provided by hooking a helper
into the new ->phy_link_change method.
