Subject: [RFC][PATCH] dt-bindings: usb: rt1711h: Add connector bindings

Add connector binding documentation for Richtek RT1711H Type-C
chip driver

It was noted by Rob Herring that the rt1711h binding docs
doesn't include the connector binding.

Thus this patch adds such documentation following the details
in Documentation/devicetree/bindings/usb/typec-tcpci.txt
