    Pretty simple test:
    - picks the hdcp capable output with suitable pipe and apply modeset.
    - checks the connected sink's hdcp capability through debugfs
    - apply a FB and wait for the flip completion.
    - clears the content protection property
    - verifies that it clears
    - sets the content protection property to desired
    - verifies that it transitions to enabled
    - incase of timeout three reattempts are implemented
    - clear the content protection property and modeset on the crtc
    Above steps are repeated on all HDCP capable connectors for both
    legacy and atomic subtests.
      dynamic subtests are dropped [Daniel]
      debugfs is used to detect the sink's hdcp capability [Daniel]
      data structure is made as global variable.
      debugfs file from connector's debugfs dir is used [Daniel]
      i915_debugfs_connector_dir() usage is modified [Chris]
