drivers/spi: ensure SPI flash is boot device for coreboot tables

The spi_flash_probe() routine was setting a global varible
    unconditonally regardless if the probe was for the boot device
    or even if the boot devcie was flash. Moreover, there's no need
    to report the SPI information if the boot device isn't even SPI.

Lastly, it's possible that the boot device is a SPI flash, but
    the platform may never probe (selecting SPI_FLASH) for the
    actual device connected. In that situation don't fill anything
    in as no correct information is known.
