Subject: [PATCH 1/4] dt-bindings: usb: gpio-sbu-mux: Add OnSemi NB7VPQ904M
 mux

The OnSemi NB7VPQ904M Type-C DP altmode redriver provides SBU signals
that can be used in with the gpio-sbu-mux driver. Document it.

Note that the -mux suffix is there to indicate that the gpio-sbu-mux
driver interacts with the mux part of this otherwise quite sophisticated
chip, leaving the "onnn,nb7vpq904m" compatible free for when a proper
driver taking care of all of the chip's capabilities is introduced.
