The partner's PD revision may be resolved later than the port partner registration since the port partner creation may take place once Type-C detects the port has changed state, but before PD communication is completed. Add a setter so that the partner's PD revision can be attached to it once it becomes available. If the revision is set to a valid version (not 0), the setter will also refresh the partner's usb_pd flag and notify on "supports_usb_power_delivery" sysfs property as well.
