grouper: power hal: improve interactive loads

-- ignore set_interactive(0) mode sets
-- decrease cpu load from 85% to 75% before ramping up; this way a core's
   frequency will be maxed out more aggressively
-- increase the hold time at max freq from 30ms to 500ms before beinning to
   ramp down; this way a core will stay longer at the maximum frequency, once
-- increase timer sampling rate from 20ms to 50ms; this way cpufreq ramdown
   will be slower
