PM: docs: intel_pstate: fix Active Mode w/o HWP paragraph

Browse source 
P-state selection algorithm (powersave or performance) is selected by
echoing the desired choice to scaling_governor sysfs attribute and not
to scaling_cur_freq (as currently stated).

Fix it.

In this mode ``intel_pstate`` registers utilization update callbacks with the
CPU scheduler in order to run a P-state selection algorithm, either
``powersave`` or ``performance``, depending on the ``scaling_cur_freq`` policy
``powersave`` or ``performance``, depending on the ``scaling_governor`` policy
setting in ``sysfs``. The current CPU frequency information to be made
available from the ``scaling_cur_freq`` policy attribute in ``sysfs`` is
periodically updated by those utilization update callbacks too.
