Without this node, there will be no palmas
driver to notify dwc3 that a cable has
been connected and, without that, dwc3
will never initialize.

Change from v2:
fix vbus-supply value after SMPS10 is modeled as 2 regulators. This is needed
after SMPS10 is modeled as 2 regulators.
[1] models SMPS10 as 2 regulators.
[2] splits the SMPS10 node into two to represent the 2 regulators.

This isn't so much a comment on this patch as the Palmas binding:

Presumably, the Palmas device contains a USB VID detector, not a whole
USB controller. I'd expect the compatible value to indicate this more
directly, i.e. be something like ti,palmas-usb-vid or
ti,palmas-usb-vid-detector.
