Subject: [PATCH 02/22] docs: thermal: convert cpu-idle-cooling.rst to ReST

Despite being named with .rst extension, this file doesn't
match the ReST standard. It actually causes a crash at
Sphinx:

	Sphinx parallel build error:
	docutils.utils.SystemMessage: /devel/v4l/docs/Documentation/driver-api/thermal/cpu-idle-cooling.rst:69: (SEVERE/4) Unexpected section title.

Add needed markups for it to be properly parsed.

While here, add it to the thermal index.rst.
