Add a compatible entry for the NXP PTN36043 GPIO-based mux hardware
used for connecting, disconnecting and switching orientation of
the SuperSpeed lines in USB Type-C applications.

PTN36043 isn't an SBU mux, so it is incorrect to declare that it is
compatible with the "gpio-sbu-mux".

Well, so I should create a compatible such as "gpio-ss-mux" and make some
changes on the driver, right?

You're aware that I already sent patches regarding this topic:

I just go through this thread. Looks like rob like use gpio mux-control to
to do that. is my understand Correct?

I browsed through your series. I think it has the same problem: it
underrepresents the SS signals. You have specified the SS signals
between the connector and PTN36043. Please also add the SS signals going
between PTN36043 and your USB host or PHY.
Moreover, there is no such thing as just "gpio-ss-mux", there is an NXP
chip which providess SS mux / switching functionality (I think the
datasheet calls it a switch, maybe that's a better name), so there
should be two compatibles for the device (like all the gpio-sbu-mux
devices have).
