libpayload: usb: xhci: Treat port reset as a port status change

If a port is connected before and after an xhci controller reset, the
    PORTSC CSC bit may not be asserted. Add an additional check in
    xhci_rh_port_status_changed for the PRC bit so we can correctly handle
    ports in such a state.
