net: phy: fix phy_disable_eee
genphy_c45_write_eee_adv() becomes a no-op if phydev->supported_eee
is cleared. That's not what we want because this function is still
needed to clear the EEE advertisement register(s).
Fill phydev->eee_broken_modes instead to ensure that userspace
can't re-enable EEE advertising.
