Subject: [PATCH 4/4] dt-bindings: phy-rockchip-inno-usb2: add new rockchip,force-bvalid property.

This property is used when the otg-id pin is not connected. When this
property is set it forces to set the B-Device Session Valid bit when the
port works as device and clears that bit when the port works as host.
