USB: serial: ch341: add new Product ID for CH340
Add PID for CH340 that's found on some ESP8266 dev boards made by LilyGO. The specific device that contains such serial converter can be seen here: https://github.com/LilyGO/LILYGO-T-OI. Apparently, it's a regular CH340, but I've confirmed with others that also bought this board that the PID found on this device (0x7522) differs from other devices with the "same" converter (0x7523). Simply adding its PID to the driver and rebuilding it made it work as expected.
