USB: more changes for v5.3 merge window

Browse source 
Turns out a few more important changes came about. We have the new
 Cadence DRD Driver being added here and that's the biggest, most
 important part.
 
 Together with that we have suport for new imx7ulp phy. Support for
 TigerLake Devices on dwc3. Also a couple important fixes which weren't
 completed in time for the -rc cycle.

*
* Important: wValue, wIndex, wLength parameters before invoking this function
* should be processed by le16_to_cpu macro.
