Subject: [PATCH] USB: serial: cp210x: add ID for MGP Instruments PDS100

The radiation meter has the text MGP Instruments PDS-100G or PDS-100GN
produced by Mirion Technologies. Tested by forcing the driver
association with

   echo 10c4 863c > /sys/bus/usb-serial/drivers/cp210x/new_id

and then setting the serial port in 115200 8N1 mode. The device
announces ID_USB_VENDOR_ENC=Silicon\x20Labs and ID_USB_MODEL_ENC=PDS100
