net: phy: respect cached advertising when re-enabling EEE

Browse Source 
If we remove modes from EEE advertisement and disable / re-enable EEE,
then advertisement is set to all supported modes. I don't think this is
what the user expects. So respect the cached advertisement and just fall
back to all supported modes if cached advertisement is empty.
