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.
BRANCH=veyron
BUG=chrome-os-partner:38352
TEST=Booted on Jerry with Servo attached.
