Implement the power on/off recommended procedure for the Single GPHY we have on our Starfighter 2 switch. In order to make sure we get proper LED link/activity signaling during suspend, switch the link indication from the Switch/MAC to the PHY. Finally, since the GPHY needs to be reset to be put in low power mode, we will loose any context applied to it: workarounds, EEE etc.. so we need to call phy_init_hw() to get our fixups re-applied successfully.
