[ Upstream commit 398fd408ccfb5e44b1cbe73a209d2281d3efa83c ]

It was reported [0] that network doesn't wake up on cable plug-in with
certain chip versions. Reason is that on these chip versions the PHY
doesn't detect cable plug-in when being in power-down mode. So prevent
the PHY from powering down if WoL is enabled.
