Update git submodules

* Update docs/submodules/pharos from branch 'master'
  - Merge "PDF: generate_config: Add IDF parsing support"
  - PDF: generate_config: Add IDF parsing support

    For a given 'podN.yaml' file, check whether a file named
    'idf-podN.yaml' exists in the same directory, and if it does,
    pass its contents under the 'idf' dict key to the j2 template.

    This assumes the contents of IDF yaml have a root 'idf' key.
