net: stmmac: make EEE depend on phy->enable_tx_lpi

Make stmmac EEE depend on phylib's evaluation of user settings and PHY
negotiation, as indicated by phy->enable_tx_lpi. This will ensure when
phylib has evaluated that the user has disabled LPI, phy_init_eee()
will not be called, and priv->eee_active will be false, causing LPI/EEE
to be disabled.

This is an interim measure - phy_init_eee() will be removed in a later
patch.
