daisy: Disable LMT from modifying max/min cpufreq.
We don't want laptop-mode tools(LMT) to manage min/max frequencies at
all. Those limits may be set prior to LMT (see bug for details).
Additionally, thermal.sh also maintains the max value so don't want
LMT undermining that.
BUG=chrome-os-partner:18927
TEST=manual, emerge
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq
And see no changes by LMT. If I instead modify patch to use explicit
frequency (say none -> 300000) I do see LMT make the change
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
300000
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq
300000
