[PATCH net-next v4 07/18] net: stmmac: clean up stmmac_disable_eee_mode()

stmmac_disable_eee_mode() is now only called from stmmac_xmit() when
both priv->tx_path_in_lpi_mode and priv->eee_sw_timer_en are true.
Therefore:
if (!priv->eee_sw_timer_en)
in stmmac_disable_eee_mode() will never be true, so this is dead code.
Remove it, and rename the function to indicate that it now only deals
with software based EEE mode.
