Adds a PID for the CH9102 chipset that can be found in some cheap ESP
development boards.

Example: LILYGO T-Display (and its S3 variant)
https://lilygo.cc/products/lilygo%C2%AE-ttgo-t-display-1-14-inch-lcd-esp32-control-board

After patching the driver to include idProduct=0x55d4 the devices work
as expected.
