This is to allow them to be referenced in a later commit. There was
also a mistake where sysFS was introduced as section 2, but numbered
as section 1. And vice versa for 'Using perf framework'. This can't
happen with unnumbered sections.

Stephen Rothwell reported htmldocs warning:
Documentation/trace/coresight/coresight.rst:133: WARNING: Inline emphasis start-string without end-string.
The warning above is due to unescaped wildcard asterisk (*) on CoreSight
devicetree binding filename, which confuses Sphinx as emphasis instead.
Escape the wildcard to fix the warning.

Each CoreSight component has slightly different requirements and
nothing applies to every component, so each CoreSight component has its
own schema document.

The conversion tools used during DocBook/LaTeX/html/Markdown->ReST
conversion and some cut-and-pasted text contain some characters that
aren't easily reachable on standard keyboards and/or could cause
troubles when parsed by the documentation build system.
Replace the occurences of the following characters:
- U+00a0 (' '): NO-BREAK SPACE
as it can cause lines being truncated on PDF output

this can help users to understand how to control the knobs for PID
tracing when the kernel is in different ELs.

There are two files in the Documentation/trace directory relating to
coresight, with more to follow, so create a Documentation/trace/coresight
directory and move existing files there. Fixup index to reference
new location.
Update MAINTAINERS to reference this sub-directory rather than the
individual files.
