USB fixes for 5.14-rc3

Browse Source 
Here are some USB fixes for 5.14-rc3 to resolve a bunch of tiny problems
 reported.  Included in here are:
 	- dtsi revert to resolve a problem which broke android systems
 	  that relied on the dts name to find the USB controller device.
 	  People are still working out the "real" solution for this, but
 	  for now the revert is needed.
 	- core USB fix for pipe calculation found by syzbot
 	- typec fixes
 	- gadget driver fixes
 	- new usb-serial device ids
 	- new USB quirks
 	- xhci fixes
 	- usb hub fixes for power management issues reported
 	- other tiny fixes
 
 All have been in linux-next with no reported problems.
