USB fixes for 4.17-rc3 

Here are a number of USB driver fixes for reported problems for
 4.17-rc3.
 
 The "largest" here is a number of phy core changes for reported problems
 with the -rc1 release.  There's also the usual musb and xhci fixes, as
 well as new device id updates.  There are also some usbip fixes for
 reported problems as more people start to use that code with containers.
 
 All of these have been in linux-next with no reported issues, except the
 last few new device ids, which are "obviously correct" :)
