google/veyron_rialto: Throttle to 1416MHz @ 1200mV in bootblock

The 1392MHz value used to throttle the RK3288 earlier was somewhat
arbitrary. This patch brings the throttling in sync with the operating
points specified in the Linux device tree for RK3288.

BUG=chrome-os-partner:42054
BRANCH=none
TEST=Saw print statement in image.serial.bin indicating that APLL
