cpufreq-cpu0 driver needs OPPs to be present in DT which can be probed by it to get frequency table. This patch adds OPPs and clock-latency to tegra cpu0 node for multiple SoCs.
Voltage levels aren't used until now for tegra and so a flat value which would eventually be ignored is used to represent voltage.
