Revert "dt-bindings: usb: qcom,dwc3: Add bindings for SC8280 Multiport"

This reverts commit ca58c4ae75.

The patches for the features that these bindings described are still
under active development, so odds are these bindings will also have to
be changed in the future.  As no in-tree code requires these bindings at
the moment, revert them.
