[PATCH] USB: ftdi_sio: Add support for HCG HF Dual ISO RFID Reader

This patch adds support for ACG Identification Technologies GmbH's HF
Dual ISO Reader (an RFID tag reader) to the ftdi_sio driver's device ID
table.  The product ID was supplied by anotonios (anton at goto10 dot
org) on the ftdi-usb-sio-devel list and subsequently verified by myself
(Ian Abbott).
