Docs/subsystem-apis: Remove '[The ]Linux' prefixes from titles of listed documents

Some documents that listed on subsystem-apis have 'Linux' or 'The Linux'
title prefixes. It's duplicated information, and makes finding the
document of interest with human eyes not easy. Remove the prefixes from
the titles.

docs: cpu-freq: convert index.txt to ReST

most of the stuff there can be re-used with ReST format,
but we need to add an empty TOC and remove the existing
entries, as the following conversion patches will be re-adding
them, as they're converted.
