cpufreq:LAB: Introduce new cpufreq LAB(Legaccy Application Boost) governor
This patch introduces new cpufreq governor named 'LAB'.
LAB governor will use scheduler, per-CPU information to determine how many
CPUs are in busy now. As a result the number of idle CPUs is calculated
for current load (digital low pass filtering is used to provide more stable
results). It will determine next frequency.
