USB / Thunderbolt fixes for 5.13-rc4

Browse Source 
Here are a number of tiny USB and Thunderbolt driver fixes for 5.13-rc4.
 
 They consist of:
 	- thunderbolt fixes for	some NVM bound issues
 	- xhci fixes for reported problems
 	- control-request fixups
 	- documentation build warning fixes
 	- new usb-serial driver device ids
 	- typec bugfixes for reported issues
 	- usbfs warning fixups (could be triggered from userspace)
 	- other tiny fixes for reported problems.
 
 All of these have been in linux-next with no reported issues.
