[v3,1/2] dt-bindings: usb: gpio-sbu-mux: Add an entry for CBDTU02043

From: Fabio Estevam <festevam@denx.de>

Add a compatible entry for the NXP CBDTU02043 GPIO-based mux hardware
used for connecting, disconnecting and switching orientation of
the SBU lines in USB Type-C applications.

Changes since v2:
- None. Splitted the dt-bindings from the dts changes so that
this series can go via the USB tree.

Changes since v1:
- None. Only collected Conor's Ack.

There seem to be very few compatibles in this file, so I guess
everything uses the generic compatible. I'm not expecting you to know
why it's like this, but should we add a compatible for this particular
mux & only relax the requirement for it specifically?

I am not sure.

Bjorn, do you have any suggestions, please?

FWIW,

although I do think that adding more compatibles if there is gonna be
divergence in capabilities is a good idea..

Cheers,
Conor.
