In order to improve the CPU performance, use schedutil cpufreq governor
as the default governor instead of powersave governor.

RPI4 supports only two CPU frequencies of 600MHz and 1500MHz.
After changed the default governor, can check the usage information
of two frequencies by schedutil governor.

[Example]
$ cat /sys/devices/system/cpu/cpu0/cpufreq/stats/time_in_state
600000 4347
1500000 2146
