Even if the Type-C controller supports PD, it is doable to disable PD capabilities with the current state machine in TCPM. Without enabling RX in low-level drivers and with skipping the power negotiation, the port is eligible to be a non-PD Type-C port. Use new flags whose values are populated from the device tree to decide the port PD capability. Adding "pd-disable" property in device tree indicates that the port does not support PD. If PD is not supported, the device tree property "typec-power-opmode" shall be added to specify the advertised Rp value if the port supports SRC role.
