[MinnowBoard] Confusing documentation about "debug" serial port.

[George Hartzell]

The documentation for the [6-Wire serial
console](http://www.elinux.org/Minnowboard:MinnowMax#6-Wire_Serial_Console)
suggests pretty strongly that CTS, VCC and RTS are hooked up to pins
2,3, and 6, respectively.

On page 8 of 29, [the
schematic](http://www.elinux.org/images/f/ff/002-0004205_reva2_SCH_PUBLIC.pdf)
shows that only pins 1, 4, and 5 are connected to anything (gnd, rx,
and tx).

The docs for the [4-Wire serial
console](http://www.elinux.org/Minnowboard:MinnowMax#4-Wire_Serial_Console)
configuration make it clear that pin 3 isn't connected to anything.

Would it be correct/clearer to say something similar for the 6-Wire
configuration?

Thanks,
