b19d76d4b0 cpufreq: fix probe method to support Intel machine 
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.

7ba791b2a7 hotplug: make hotplug probing more robust 
In general it makes not sense to hotplug out all the CPUs of a system, thus
ususally CPU0 is configured as not hot/plugggable.
Definitively, on a single core system it does not make sense to hotpolug out
the only available CPU.

This patch switch to usage of CPU1 for hotplug support probing, which is the
really first one for which enabling hotplug could be useful.
