[PATCH] USB: support for USB-to-serial cable from Speed Dragon Multimedia

The USB data cable for my Samsung GSM phone contains the USB-to-serial
converter chip MS3303H from Speed Dragon Multimedia, Inc.  that appears to
be compatible with the PL2303 chip.  The following patch adds support for
this chip to the pl2303 driver.
