Emanuele Ghidoli 12a895faa0 net: phy: dp83867: Disable EEE support as not implemented 
[ Upstream commit 84a905290c ]

While the DP83867 PHYs report EEE capability through their feature
registers, the actual hardware does not support EEE (see Links).
When the connected MAC enables EEE, it causes link instability and
communication failures.

The issue is reproducible with a iMX8MP and relevant stmmac ethernet port.
Since the introduction of phylink-managed EEE support in the stmmac driver,
EEE is now enabled by default, leading to issues on systems using the
DP83867 PHY.

Call phy_disable_eee during phy initialization to prevent EEE from being
enabled on DP83867 PHYs.
