Hi,

This is a rework of stmmac's EEE support in light of the addition of EEE
management to phylib.

Patch 1 adds configuration of the receive clock phy_eee_rx_clock_stop()
(which was part of another series.)

Patch 2 moves the tracking of tx_lpi_timer to phylib.

Patch 3 makes stmmac EEE state depend on phylib's enable_tx_lpi flag.

Patch 4 removes redundant code from the ethtool EEE operations.

Patch 5 removes the driver private tx_lpi_enabled, which will now be
managed by phylib.

Patch 6 removes the dependence of EEE error statistics on the EEE
enable state, instead depending on whether EEE is supported by the
hardware.

Patch 7 removes phy_init_eee(), instead using phy_eee_rx_clock_stop()
to configure whether the PHY may stop the receive clock.
