Diego Herranz 5a6f0495db tcl/interface/ftdi: improve minimodule config
- Tested on a real FT2232H MiniModule, so warning removed.
- Every pin initially set to high impedance except TCK, TDI,
  TDO and TMS: Safest values given it's an evaluation board
  and the rest of pins might be connected to something else.
- Reset is now initially de-asserted (it was asserted
  which is not recommended).
- nRST pin choice is arbitrary so comment added (wondering
  if it should be an "echo").
- "-oe" option added to NRST signal so it can be set as
  high impedance (tri-stated).
