dt-bindings: usb: Add support for Terminus FE1.1s USB2.0 Hub controller
Terminus FE1.1s is USB2.0 protocol compliant 4-port USB HUB, It support MTT (Multiple Transaction Translator) mode, the upstream port supports high-speed 480MHz and full-speed 12MHz modes, also has integrated 5V to 3.3V, 1.8V regulator and Power-On-Reset circuit. Introduce the DT binding for it.
