Picked upstream commit 83810f84ecf11dfc5a9414a8b762c3501b328185 instead
of the SAUCE version. Note this has the order of turning off USB2 and
USB3 ports turned around compared to the SAUCE patch (first USB2, then
USB3).

Bug description:
[Impact]
USB storage can be stuck in USB reset loop after reboot. More reboots
don't help the situation, unless it's re-plugged.
[Fix]
Power cycle USB ports on system shutdown/reboot.
[Test]
The USB storage survived 300 times of reboots, and it works under each
reboot cycle.
[Where problems could occur]
One potential problem I can think of is S5 WoL over USB ethernet. Since
the port power and its associated ACPI power are turned off, WoL may
stop working, if WoL over USB is a thing.
