Brooks Davis c9e7c6f4fb Add support to the uftdi driver for Intrepid Control Systems' vehicle
bus interfaces.  These interfaces use the FTDI chipset with different
Vendor and Product IDs.

Add two additional baud rate enumerations.  The vehicle bus interfaces
use a baud rate of 2000000.  Also add 3000000 as it is the other FTDI
baud divisor special case.

I've commited a slightly different patch from that provided in the PR as
I changed the matching code a bit yesterday.
