net: cadence: macb: add ethtool EEE support
Implement get_eee and set_eee ethtool ops for GEM as simple passthroughs
to phylink_ethtool_get_eee() and phylink_ethtool_set_eee().
No MACB_CAPS_EEE guard is needed: phylink returns -EOPNOTSUPP from both
ops when mac_supports_eee is false, which is the case when
lpi_capabilities and lpi_interfaces are not populated. Those fields are
only set when MACB_CAPS_EEE is present (previous patch), so phylink
already handles the unsupported case correctly.
