flashrom: Only find "unknown .. SPI chip" if no other chip was found
This removes the false positive matches we've been seeing, and also removes
the true positive match in case there is more than one flash chip and the 2nd
or 3rd are unknown - but I think that case is uncommon enough to warrant the
improvement in the common case. Use flashrom -frc forced read if you have the
uncommon case, and/or please add the flash chip to the flashchips array.
