devices, because they need an unlock command first.
For this reason, ST M50FLW support is moved to a
new HW support module, because any change in jedec.c
would bear the risk to cause problems with the already
supported devices.

It's already tested with ST M50FLW080A; the other
chips of this family i dont have available, so i couldnt
test it.
