Add fallback functions for programmer shutdown and memory mapping and fix FT2232 and IT87
FT2232 and IT87 programmers used functions of the dummy programmer
instead of fallback functions.
The dummy programmer is a "real" programmer with possible side effects
and its functions should not be abused by other programmers. Make
FT2232 and IT87 use official fallback functions instead. Create
fallback_shutdown(). Create fallback_chip_writeb(). Convert the
programmer #defines to an enum.
Corresponding to flashrom svn r678.
