When calling device_add in the registration of typec_port, it will do
the NULL check on usb_power_delivery handle in typec_port for the
visibility of the device attributes. It is always NULL because port->pd
is set in typec_port_set_usb_power_delivery which is later than the
device_add call.

Set port->pd before device_add and only link the device after that.
