Documentation: coresight: fix make refcheckdocs warning

This reference uses a glob pattern to match multiple files, but the
asterisk was escaped as \* in order to not be interpreted by sphinx
as reStructuredText markup.

refcheckdocs/documentation-file-ref-check doesn't know about rST syntax
and tries to interpret the \* literally (instead of as a glob).

We can work around the warning by putting the Documentation reference
inside double backticks (``..``), which allows us to not escape the
asterisk.
