Update git submodules

* Update docs/submodules/ccsdk/parent.git from branch 'master'
  to 8aa219f29e167aaab19da4feef4463409e7b624d
  - Revert "Update ccsdk version to released version"

    This reverts commit ddb25bf029f6203d50ee127e053b1bd32228384f.
    This change was not necessary, since staging job already strips -SNAPSHOT
    from pom.xmls : so when you compile against released version of
    parent pom, it'll already depend on released version of CCSDK
    artifacts.  Cool!
