ipq806x: set PERFORMANCE as the default cpufreq governor
Move default cpufreq governor from ONDEMAND to PERFORMANCE. The temp
increase is just 2°C and Watt usage the change is minimal in the order
of additional millwatt. The SoC and krait in general looks to suffer for
some problem with cache scaling. To have better system stability, force
cpu freq and cache freq to the max value supported by the system. This
follows mvebu platform where cpufreq is broken and cause minimal
temp/watt increase.
User can still tweak the governor to ondemand using sysfs entry if
needed.
