Ian Lepore 74855db616 Remove device type from the uftdi_devs table, enhance the jtag-skip feature.
Device type and revision is now determined from the bcdDevice field and
doesn't need to be in the table at all.  The feature that skips creation
of /dev/ttyU* entries for jtag and gpio interfaces is enhanced:

 - The feature is now optional, but enabled by default.  A tunable and
   sysctl are available to control it: hw.usb.uftdi.skip_jtag_interfaces.
 - We no longer assume interface #0 is the only jtag interface.  Up to
   eight interfaces per chip can be flagged as jtag.  (Current ftdi chips
   support a max of 4 interfaces; this leaves room for growth.)
 - Some manufacturers don't change the product ID or use the same ID for
   different devices intended for both serial-comms and jtag/gpio use.
   Often while the product ID is the same, the product name string is
   different, so it's now possible to search for the product name in a
   table of strings and get the set of non-tty interfaces from that table.
