Reorganize the power management part of admin-guide by adding a
description of major power management strategies supported by the
kernel (system-wide and working-state power management) to it and
dividing the rest of the material into the system-wide PM and
working-state PM chapters.
On top of that, add a description of system sleep states to the
system-wide PM chapter.

Add a document describing the current behavior and user space
interface of the intel_pstate driver in the RST format and
drop the existing outdated intel_pstate.txt document.
Also update admin-guide/pm/cpufreq.rst with proper RST references
to the new intel_pstate.rst document.

The user/admin documentation of cpufreq is badly outdated. It
conains stale and/or inaccurate information along with things
that are not particularly useful. Also, some of the important
pieces are missing from it.
For this reason, add a new user/admin document for cpufreq
containing current information to admin-guide and drop the old
outdated .txt documents it is replacing.
Since there will be more PM documents in admin-guide going forward,
create a separate directory for them and put the cpufreq document
in there right away.
