msm: thermal: Clean up msm cpufreq function calls

Remove msm_cpufreq_set_freq_limits and register with
CPUFREQ_POLICY_NOTIFIER to get immediate update on cpu frequencies
as long as a cpufreq_update_policy is called. Ensure that when
cpufreq_update_policy is called, cpu will not be hotplugged by
calling get_online_cpus().
