ENGR00163052: CPUFREQ does not report correct frequency
When DVFS_CORE is enabled, the following command reports incorrect frequency:
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq
Fix this by ensuring the CPUFREQ does not change the frequency
when DVFS_CORE is active. And DVFS-CORE informs CPUFREQ of the
change done to CPU frequency.
