[PATCH v3 2/2] dt-bindings: usb: ptn5110: add TCPC properties

["Miao.Zhu" <Miao.Zhu@synopsys.com>]

From: Miao Zhu <miao@synopsys.com>

The TCPCI driver has flags to configure its protperties but
no way to enable these flags yet. Add these flags into DT
so that the driver can be compatible with TCPCI  Spec R2 V1.0.
