cpufreq: interactive: run at fraction of hispeed_freq when load is low
When load is below go_hispeed_load, apply the percentage of CPU load to
a max frequency of hispeed_freq instead of the max speed. This avoids
jumping too quickly to hispeed_freq when it is a relatively low
percentage of max speed. This also allows go_hispeed_load to be set to
a high percentage relative to hispeed_freq (as a percentage of max speed,
again useful when hispeed_freq is a low fraction of max speed), to cap
larger loads at hispeed_freq. For example, a load of 60% will typically
move to 60% of hispeed_freq, not 60% of max speed. This causes the
governor to apply two different speed caps, depending on whether load is
below or above go_hispeed_load.
Also fix the type of hispeed_freq, which was u64, to match other
speed data types (and avoid overhead and allow division).
