Subject: [PATCH 3/3] dt-bindings: usb: fsa4480: Add compatible for OCP96011

The Orient-Chip OCP96011 is generally compatible with the FSA4480, add a
compatible for it with the fallback on fsa4480.

However the AUX/SBU connections are expected to be swapped compared to
FSA4480, so document this in the data-lanes description.
