This patch introduces new methods needed by the USB-Serial Serial Core
version. The methods are:
pl2303_stop_tx(), pl2303_send_xchar(), pl2303_stop_rx(), pl2303_type(),
pl2303_enable_ms(), pl2303_release_port(), pl2303_request_port(),
pl2303_config_port(), pl2303_verify_port().
Note that, however, some of them do nothing. That's because I _think_ they
are not needed.
