cpufreq: fix probe method to support Intel machine

Browse Source 
Recent Intel machines uses the CPUFreq pstate driver, which does not create
the standard "/sys/devices/system/cpu/cpufreq" folder usually created by
other (mostly ARM platform) drivers.

This patch fixes the probe method to check for the propert pstate driver
being available in order to enabled the CPUFreq module.
