docs: thermal: convert to ReST

Rename the thermal documentation files to ReST, add an
index for them and adjust in order to produce a nice html
output via the Sphinx build system.

At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.

 The generic cpu cooling(freq clipping) provides registration/unregistration APIs
 to the caller. The binding of the cooling devices to the trip point is left for
 the user. The registration APIs returns the cooling device pointer.
