cpufreq: pcc-cpufreq: update default value of cpuinfo_transition_latency
The cpufreq documentation specifies policy->cpuinfo.transition_latency the time it takes on this CPU to switch between two frequencies in nanoseconds (if appropriate, else specify CPUFREQ_ETERNAL) currently pcc-cpufreq does not expose the value and sets it to zero. I changed the pcc-cpufreq driver and it's documentation to conform to the default value specified in Documentation/cpu-freq/cpu-drivers.txt Signed-off-by: Jacob Tanenbaum <jtanenba@redhat.com> Acked-by: Viresh Kumar <viresh.kumar@linaro.org> Signed-off-by: Rafael J.
