SPI read speed directly impacts boot time and we do quite a lot of reading. Add a way to easily find out the speed of SPI flash reads within coreboot. Write speed is less important since there are very few writes and they are small. BUG=chrome-os-partner:56556 BRANCH=none TEST=run on gru with SPI_SPEED_DEBUG set to 1.
