USB fixes for 5.13-rc6

Browse Source 
Here are a number of tiny USB fixes for 5.13-rc6.
 
 There are more than I would normally like, but there's been a bunch of
 people banging on the gadget and dwc3 and typec code recently for I
 think an Android release, which has resulted in a number of small fixes.
 It's nice to see companies send fixes upstream for this type of work, a
 notable change from years ago.
 
 Anyway, fixes in here are:
 	- usb-serial device id updates
 	- usb-serial cp210x driver fixes for broken firmware versions
 	- typec fixes for crazy charging devices and other reported
 	  problems
 	- dwc3 fixes for reported problems found
 	- gadget fixes for reported problems
 	- tiny xhci fixes
 	- other small fixes for reported issues.
 	- revert of a problem fix found by linux-next testing
 
 All of these have passed 0-day and linux-next testing with no reported
 problems (the revert for the found linux-next build problem included).
