sched: Print max frequency in sched_get_task_cpu_cycles trace point 



Scheduler knows max frequency allowed by both thermal driver and
cpufreq. cpu_max_freq() returns the minimum of these two. Printing it
in sched_get_task_cpu_cycles() is useful in understanding the actual
frequency and limits vs cpufreq view of the frequency and limits.
