tegra124: Correct cpu power on sequence and CPUPWRGOOD_TIME
Based on TRM, cpu clock enabling and reset vector setting should all be done properly before ungating cpu power partition. Otherwise, with current code, a race condition could occur where cpu starts but reset vector has not been set. BUG=chrome-os-partner:30064 BRANCH=none TEST=run nyan_big reboot test. No issue is experienced.
