USB fixes for 5.6-rc7

Browse Source 
Here are some small USB fixes for 5.6-rc7.  And there's a thunderbolt
 driver fix thrown in for good measure as well.
 
 These fixes are:
 	- new device ids for usb-serial drivers
 	- thunderbolt error code fix
 	- xhci driver fixes
 	- typec fixes
 	- cdc-acm driver fixes
 	- chipidea driver fix
 	- more USB quirks added for devices that need them.
 
 All of these have been in linux-next with no reported issues.
