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.
