[PATCH] USB: ftdi_sio: add support for Eclo COM to 1-Wire USB adapter

This patch adds support for the Eclo COM to 1-Wire USB adapter
<http://www.eclo.pt/products_ibutton_adapters_usb01_en.asp> to the
ftdi_sio driver's device ID table.  Details were provided by Martin
Grill on the ftdi-sio-usb-devel mailing list and I (Ian Abbott)
confirmed it matched the INF file in the Eclo's Windows driver package.
