Marcel & all,

Here is an updated version of the STLC2500 patch. Compared to previous 
patch versions, it adds support to speeds up to 4000000 bps.

* Add support for speed up to 4000000 bps.
* Makes the firmware & parameters download optional : even though those 
are supposed to be mandatory, practive shows that the chip can run 
without them.
* Cleanup the speed setting step : call the Ericsson routines directly 
instead of duplicating the code.
* Reset the chip only once after all settings & downloads have been done.

Cheers,

Fabien
