[flashrom] [PATCH] Dediprog SF100 support

Dediprog SF100 support. Very fragile, lots of stuff guessed from logs.
May explode spontaneously.
I think I know enough to actually use it to ID the chip, but that's it.
A USB log with which includes writing an image from the original
software (pretty much any image) would help clear up a few ambiguities.
