net: bcmgenet: Fix EEE implementation
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
Fixes: 6ef398ea60d9 ("net: bcmgenet: add EEE support")
