Why wasn't it there before? USB did not have VBUS?
Explanation is so incomplete I suspect you are patching broken things,
so as well this could be completely different hardware (e.g. there is no
regulator for this block but e.g. connector).

Drop redundant part. This cannot be anything else than phandle and
regulator.
"VBUS power supply" for example. But anyway, I don't have certainty that
this is correct hardware representation. It's your task to provide that.
