usb: patches for v4.1 merge window

Browse source 
As usual, a big pile of commits. This time a total
 of 111 non-merge commits.
 
 Other than the usual set of cleanups and non-critical
 fixes, we have some interesting work for AM335x's MUSB
 babble recovery. Now that takes a lot less time and we
 don't have to Reset MUSB all the time.
 
 The printer gadget has been converted to configfs interface
 and the atmel udc has learned suspend/resume with wakeup.
