Commit Message

  Migrate from genphy_config_eee_advert() to genphy_c45_write_eee_adv().

It should work as before except write operation to the EEE adv registers
will be done only if some EEE abilities was detected.

If some driver will have a regression, related driver should provide own
.get_features callback. See micrel.c:ksz9477_get_features() as example.
