USB: changes for v5.8 merge window

Rather busy cycle. We have a total 99 non-merge commits going into v5.8
merge window. The majority of the changes are in dwc3 this around (31.7%
of all changes). It's composed mostly Thinh's recent updates to get dwc3
to behave correctly with stream transfers. We have also have Roger's for
Keystone platforms and Neil's updates for the meson glue layer.

Apart from those, we have the usual set of non-critical fixes, new
device IDs, spelling fixes all over the place.
