====================
net: phy: add and use helper phy_advertise_eee_all

Per default phylib preserves the EEE advertising at the time of
phy probing. The EEE advertising can be changed from user space,
in addition this helper allows to set the EEE advertising to all
supported modes from drivers in kernel space.
