USB: Changes for v5.4 merge window

With only 45 non-merge commits, we have a small merge window from the
Gadget perspective.

The biggest change here is the addition of the Cadence USB3 DRD
Driver. All other changes are small, non-critical fixes or smaller new
features like the improvement to BESL handling in dwc3.
