hanzj 118bf9b52d docs: Fix duplicate toctree references causing build warnings
Several documentation files are referenced in multiple toctrees,
causing Sphinx build warnings like:

  document is referenced in multiple toctrees: [...], selecting: [...]

Fix by narrowing glob patterns in parent toctrees to only match
subdirectory index files, and replacing a toctree directive with
a :doc: cross-reference:

- platforms/arm/index.rst: glob */* -> */index
- platforms/index.rst: glob */* -> */index
- guides/changing_systemclockconfig.rst: toctree -> :doc: ref

Fixes #14785
