Add a dummy SPI controller driver, similar to the dummy LPC/FWH/Parallel flasher driver
Does not support reading or writing the fake chip yet. flashrom --programmer dummy also enables the dummy SPI controller driver. Testing the dummy SPI driver revealed a RDID debug printing bug in the SPI core. Fix that as well. Corresponding to flashrom svn r507.
