[flashrom] [PATCH] Compile out FT2232 SPI if not selected

[Carl-Daniel Hailfinger]

If FT2232H SPI is not enabled, it should be compiled out completely. We
can't remove ft2232_spi.o from unconditional OBJS yet due to our
makefile structure (make features), but this patch adds #ifdefs around
all FT2232H code, so the net effect is the same.

This is 0.9.1 material.
