From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>

Convert ti,hd3ss3220.txt to YAML. Updated the binding documentation
as graph bindings of this device model Super Speed (SS) data bus to
the Super Speed (SS) capable connector.

+description: |-
+  HD3SS3220 is a USB SuperSpeed (SS) 2:1 mux with DRP port controller. The device provides Channel
+  Configuration (CC) logic and 5V VCONN sourcing for ecosystems implementing USB Type-C. The
+  HD3SS3220 can be configured as a Downstream Facing Port (DFP), Upstream Facing Port (UFP) or a
+  Dual Role Port (DRP) making it ideal for any application.
