Florian Fainelli 9f53d24852 net: bcmgenet: Fix EEE implementation
commit a9f31047baca57d47440c879cf259b86f900260c upstream.

We had a number of short comings:

- EEE must be re-evaluated whenever the state machine detects a link
  change as wight be switching from a link partner with EEE
  enabled/disabled

- tx_lpi_enabled controls whether EEE should be enabled/disabled for the
  transmit path, which applies to the TBUF block

- We do not need to forcibly enable EEE upon system resume, as the PHY
  state machine will trigger a link event that will do that, too
