cpufreq: interactive: Modifying sync_freq implementation [Rohit Gupta]

1. Check for up_threshold_any_cpu_freq instead of sync_freq to boost the frequency to sync_freq.
2. Change the load threshold name from sync_freq_load_threshold to up_threshold_any_cpu_load
3. Do not consider CPUs with load less than up_threshold_any_cpu_load while evaluating max load across CPUs
