net: dsa: allow switches driver to implement get/set EEE
Allow switches driver to query and enable/disable EEE on a per-port basis by implementing the ethtool_{get,set}_eee settings and delegating these operations to the switch driver. set_eee() will need to coordinate with the PHY driver to make sure that EEE is enabled, the link-partner supports it and the auto-negotiation result is satisfactory.
