Ian Lepore 5c16a31f9d Flag the first interface on a KTLINK FTDI-based jtag+uart device as being 
the jtag port, so that a tty is not created for it.

This is based on information in the PR and from the vendor website.  When
the PR was first opened we had no facility for flagging the jtag ports.  I
stumbled across the still-open PR with the idea of closing it, and noticed
that this wee update was needed.

* IO buffer sizes and FTDI device procotol sizes.
*
* Note that the output packet size in the following defines is not the usb
* protocol packet size based on bus speed, it is the size dictated by the FTDI
* device itself, and is used only on older chips.
*
* We allocate buffers bigger than the hardware's packet size, and process
* multiple packets within each buffer. This allows the controller to make
* optimal use of the usb bus by conducting multiple transfers with the device
* during a single bus timeslice to fill or drain the chip's fifos.
*
* The output data on newer chips has no packet header, and we are able to pack
* any number of output bytes into a buffer. On some older chips, each output
* packet contains a 1-byte header and up to 63 bytes of payload. The size is
* encoded in 6 bits of the header, hence the 64-byte limit on packet size. We
* loop to fill the buffer with many of these header+payload packets.
*
* The input data on all chips consists of packets which contain a 2-byte header
* followed by data payload. The total size of the packet is wMaxPacketSize
* which can change based on the bus speed (e.g., 64 for full speed, 512 for
* high speed). We loop to extract the headers and payloads from the packets
* packed into an input buffer.
