Split spi.c into programmer and chip code Remove chipdriver.h include from flash.h

Some of the spi programmer drivers required chipdrivers.h, needs fixing later:
  it87spi.c
  ichspi.c
  sb600spi.c
  wbsio_spi.c
  buspirate_spi.c
  ft2232spi.c
  bitbang_spi.c
  dediprog.c

Corresponding to flashrom svn r914.
