Move generic programmer function into newly introduced programmer.c
Some programmers (most notably FT2232SPI) use fallback_* and noop_*, but those functions lived inside internal.c and were unavailable if no PCI-based programmers were compiled in. Move those functions to the new file programmer.c. Thanks to Patrick Georgi for finding this. Corresponding to flashrom svn r829.
