Bus Pirate support needs serial communication
Serprog already has such functionality, so it makes sense to share that.
TODO: Factor out serial communication into a separate file, have that
code be available even if serprog is not selected and make it portable
(it is very Linux-centric right now).
Corresponding to flashrom svn r768.
