James Clark 32ee00d86e Documentation: coresight: Link config options to existing documentation
In order to document the newly added branch_broadcast option, create a
table that links all of the config option formats to any existing docs.
That way when the branch broadcast docs are expanded they are accessible
from both places.

Mauro Carvalho Chehab 90f40f514f docs: trace: coresight: coresight-etm4x-reference.rst: replace some characters
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
