[PATCH] dsa: slave: eee: Allow ports to use phylink

[Andrew Lunn <andrew@lunn.ch>]

For a port to be able to use EEE, both the MAC and the PHY must
support EEE. A phy can be provided by both a phydev or phylink. Verify
at least one of these exist, not just phydev.

Fixes: aab9c4067d23 ("net: dsa: Plug in PHYLINK support")
