  To: igt-dev, daniel

Pretty simple test:
- picks the hdcp capable output
- chooses the PIPE and apply modeset
- 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

Does this in separate sub-test for both legacy and atomic for
each connector with valid pipe.
