USB fixes for 5.16-rc6 

Here are a number of small USB driver fixes for reported problems for
 5.16-rc6.  They include:
 	- dwc2 driver fixes
 	- xhci driver fixes
 	- cdnsp driver fixes
 	- typec driver fix
 	- gadget u_ether driver fix
 	- new quirk additions
 	- usb gadget endpoint calculation fix
 	- usb serial new device ids
 	- revert of a xhci-dbg change that broke early debug booting
 
 All changes, except for the revert, have been in linux-next with no
 reported problems.  The revert was from yesterday, and it was reported
 by the developers affected that it resolved their problem.
