USB: changes for v5.10 merge window

Most of changes are on dwc3 (38.8%) with cdns3 falling close
behind (24.1%).

The biggest changes here are a series of non-critical fixes to corner
cases on dwc3, produced by Thinh N, and a series of major improvements
to cdns3 produced by Peter C.

We also have the traditional set of new device support (Intel Keem
Bay, Hikey 970) on dwc3. A series of sparse/coccinelle and checkpatch
fixes on dwc3 by yours truly and a set of minor changes all over the
stack.
