google/veyron_*: Increase SPI flash frequency to 24.75MHz
This patch increases the SPI clock for the ROM to 24.75MHz on all rk3288 (veyron) boards. This increases flash read speeds (and thereby decreases boot time) significantly, but we don't seem to get any more increases by going even higher. We have also seen occasional read failures at higher speeds in certain configurations, so this frequency seems to be the best option.
