From: Ruchi Kandoi <kandoiruchi@google.com>
When the load was below go_hispeed_load, there is a possibility that choose_freq() would return a frequency which would be higher than the hispeed_freq. According to the policy we should first jump to the hispeed_freq, stay there for above_hispeed_delay and then be allowed to raise higher than that.
Added a check to prevent the frequency to be directly raised to something higher than the hispeed_freq.
