USB/PHY fixes for 4.15-rc6

Browse Source 
Here are a number of small USB and PHY driver fixes for 4.15-rc6.
 
 Nothing major, but there are a number of regression fixes in here that
 resolve issues that have been reported a bunch.  There are also the
 usual xhci fixes as well as a number of new usb serial device ids.
 
 All of these have been in linux-next for a while with no reported
 issues.
