[flashrom] [PATCH] Share serprog serial port code

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).
