cpufreq: interactive: Ramp up to policy->max for heavy new task
New tasks don't have sufficient history to predict its behavior, even
with scheduler's help. Ramping up conservatively for a heavy task
could hurt performance when it's needed. Therefore, separate out new
tasks' load with scheduler's help and ramp up more aggressively if new
tasks make up a significant portion of total load.
