Ok. I'll attach a new patch to the series, which will fix it for all uncompatible
nodes. (Though the node with "^dwusb@" has got a comment, that the node-name
should be like that due to some compatibility reasons...)

I doubted which clock names to use here, so I've utilized the names selected by the
core Databook for the corresponding clocks. Anyway. Ok. I'll replace them with the
strings enumerated below.

Yeah. That was the best schema I could come up with to get the original
bindings. Alas there are various clock-names have been used at some
DWC USB3-compatible DT nodes, so I couldn't just set a stricter restriction
here.
