Fix Luminary FT2232 layout docs/configs
Most of this patch updates documentation and comments for various
Luminary boards, supporting two bug fixes by helping to make sense
of the current mess:
- Recent rev C lm3s811 eval boards didn't work. They must use
the ICDI layout, which sets up some signals that the older
boards didn't need. This is actually safe and appropriate
for *all* recent boards ... so just make "luminary.cfg" use
the ICDI layout.
- "luminary-lm3s811.cfg", was previously unusable! No VID/PID;
and the wrong vendor string. Make it work, but reserve it
for older boards where the ICDI layout is wrong.
- Default the LM3748 eval board to "luminary.cfg", like the
other boards. If someone uses an external JTAG adapter, all
boards will use the same workaround (override that default).
The difference between the two FT2232 layouts is that eventually
the EVB layout will fail cleanly when asked to enable SWO trace,
but the ICDI layout will as cleanly be able to enable it. Folk
using "luminary.cfg" with Rev B boards won't see anything going
wrong until SWO support is (someday) added.
