cpufreq: interactive governor: default timer 10ms, maxspeed load 95%

Modify default timer from 30ms to 10ms, sampling 2 jiffies after
idle exit on ARM as in Honeycomb.

Modify default go_maxspeed_load from 85% loaded to 95% loaded, for
use in phones where power savings is more important (tablets may be
best served overriding this).
