phy: qcom-sgmii-eth: relax order of .power_on() vs .set_mode*()

Browse Source 
Allow any order of the .power_on() and .set_mode*() methods as per the
recent discussion. This means phy_power_on() with this SerDes will now
restore the previous setup without requiring a subsequent
phy_set_mode*() call.
