MLK-16477 cpufreq: imx8: switch cpufreq governor to schedutil for multi-cluster

For multi-cluster platforms like i.MX8QM, the best cpufreq
governor is schedutil, as common cpufreq framework decides
default cpufreq governor in static compile, so this patch
adds dynamic switch of cpufreq governor according to cluster
number, changing it via sysfs interface, although it is
ugly, but it realizes dynamic cpufreq governor select for
users.
