USB: changes for v5.2 merge window

With a total of 50 non-merge commits, this is not a large pull
request. Most of the changes are, again, in dwc2 (37%) and dwc3 (32%)
with the rest of it scattered among other UDCs, function drivers and
device-tree bindings.

No really big feature this time around apart from support to Amlogic
being added to both dwc3 and dwc2 drivers.
