USB/PHY patches for 4.11-rc1

Browse source 
Here is the big USB and PHY driver updates for 4.11-rc1.
 
 Nothing major, just the normal amount of churn in the usb gadget and dwc
 and xhci controllers, new device ids, new phy drivers, a new usb-serial
 driver, and a few other minor changes in different USB drivers.
 
 All have been in linux-next for a long time with no reported issues.
