相同固件，不同设备大核最高可设置主频为什么不一致？有的是2.2G、有的是2.3G。
//第一种大核主频最高2256000
cat /sys/devices/system/cpu/cpufreq/policy4/scaling_available_frequencies
408000 600000 816000 1008000 1200000 1416000 1608000 1800000 2016000 2208000 2256000
//第二种大核主频最高2304000
cat /sys/devices/system/cpu/cpufreq/policy4/scaling_available_frequencies
408000 600000 816000 1008000 1200000 1416000 1608000 1800000 2016000 2208000 2304000
看dts，这些频率都没有disable掉。
