pass-hal: tw3: Change sysfs node to control min/max frequency of CPU

When change the maximum cpu frequency with node[1], it doesnt' change
the value of /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq.
[1] /sys/devices/system/cpu/cpufreq/pmqos/cpufreq_max

So, change the sysfs node to control min/max cpu frequency with following
nodes:
- /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
- /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq
