Update the list of devices supported by the FTDI driver. It might be
that the wrong UART reference clock will be used for a few of the IDs.
It is currently not possible to figure that out because the Linux FTDI
driver detects this run-time and not compile time based on the bcdDevice
field of the USB device descriptor. Some of the ID's in usbdevs are not
sorted according to the product ID value. Please feel free to fix this.
I'm out of my xemacs magic today.
