USB: serial: ch341: New VID/PID for CH341 USB-serial

Recent USB-serial devices using the WinChipHead CH340/CH341 chipset are
being shipped with a new vendor/product ID code pair, but an otherwise
identical device.  (This is confirmed by looking at INF for the included
Windows driver.)

Patch is tested and working, both with new and old devices.
