The pexpect module exposes a fdpexpect class starting from version 4.0.
This patch makes uses of the proper pxssh import statement depending on the
version of pexpect available in the host.

When "load_default_modules" is set to False at target initialisation time
but the "bl" module is explicitly required, the initialization of this module
fails because the system as not yet been identified as a big.LITTLE.
This identification is performed by platform.update_from_target.
This patch post-pone modules initialisation at the end of the connection
method to ensure that all the required information are available at modules
probe time.

On some machines, when a different CPUFreq policy could be configured
for each CPU, there is not a top-level 'cpufreq' folder exposed
at top level but just per-CPU ones.
This patch makes the probing for CPUFreq support more robust by checking
on all the supported paths.

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.

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.
