ixgbe: E610: do not fill EEE lp_advertised from local PHY caps

ixgbe_get_eee_e610() fills kedata->lp_advertised from pcaps.eee_cap
returned by ixgbe_aci_get_phy_caps() with IXGBE_ACI_REPORT_ACTIVE_CFG.
That report mode (and the other IXGBE_ACI_REPORT_* modes) describe the
local PHY only, not the link partner. The X550 path uses a separate
FW_PHY_ACT_UD_2 activity for partner data; the E610 ACI has no
equivalent.

Leave lp_advertised zeroed via the existing linkmode_zero() and drop
the now-unused ixgbe_eee_cap_map[]. eee_active/eee_enabled are
unaffected (sourced from link.eee_status).
