Sven Peter bc148def89 phy: apple: atc: Reset USB2 PHY during probe as well 
Now that the upstream Type-C PHY code is getting broader test coverage we
got reports of USB devices plugged in during boot or those plugged in for
the first time after boot occasionally not working correctly.
This is partially caused by the USB2 parts of the PHY being left in an
unknown state by the previous boot stages. We reset all other parts during
probe but forgot about the USB2 PHY so let's fix that and actually reset
and power off the USB2 PHY as well.
