USB/Thunderbolt fixes for 5.9-rc5 

Here are some small USB and Thunderbolt driver fixes for 5.9-rc5.
 
 Nothing huge, just a number of bugfixes and new device ids for problems
 reported:
 	- new USB serial driver ids
 	- bug fixes for syzbot reported problems
 	- typec driver fixes
 	- thunderbolt driver fixes
 	- revert of reported broken commit
 
 All of these have been in linux-next with no reported issues.
