net: dsa: b53: remove eee_enabled/eee_active in b53_get_mac_eee()
b53_get_mac_eee() sets both eee_enabled and eee_active, and then
returns zero.
dsa_user_get_eee(), which calls this function, will then continue to
call phylink_ethtool_get_eee(), which will return -EOPNOTSUPP if there
is no PHY present, otherwise calling phy_ethtool_get_eee() which in
turn will call genphy_c45_ethtool_get_eee().
genphy_c45_ethtool_get_eee() will overwrite eee_enabled and eee_active
with its own interpretation from the PHYs settings and negotiation
result.
Thus, when there is no PHY, dsa_user_get_eee() will fail with
-EOPNOTSUPP, meaning eee_enabled and eee_active will not be returned to
userspace. When there is a PHY, eee_enabled and eee_active will be
overwritten by phylib, making the setting of these members in
b53_get_mac_eee() entirely unnecessary.
Remove this code, thus simplifying b53_get_mac_eee().
