[PATCH 1/2] Documentation: coresight: Extend title heading syntax in TPDM and TPDA documentation

[Bagas Sanjaya]

kernel test robot reported htmldocs warnings:

Documentation/trace/coresight/coresight-tpda.rst:3: WARNING: Title overline too short.
Documentation/trace/coresight/coresight-tpdm.rst:3: WARNING: Title overline too short.

Extend title heading syntax (overline and underline) to match title text to
fix these warnings.

While at it, trim unneeded period in the title text.
