Subject: [PATCH 1/2] dt-bindings: usb: add NXP PTN36502 Type-C redriver bindings

Document bindings for this Type-C USB 3.1 Gen 1 and DisplayPort v1.2
combo redriver.

The PTN36502 can also run in GPIO mode where it is configured
differently, without any I2C connection, but this is not supported yet.
