intelli_plug: older Qualcomm kernel compatibility fixup

ARGH... really angry at CAF code.

some cpufreq driver APIs are incredibly unstable with some of the older
MSM kernels.  The correct way is the fix the cpufreq drivers, but there are
tons of variations out there, so rather than depending on a fix, make
intelli_plug more universal by avoiding the troubling APIs altogether
