Pretty simple test:
- initializes the output
- clears the content protection property
- verifies that it clears
- sets the content protection property to desired
- verifies that it transitions to enabled
Does this for both legacy and atomic.
Changes in v2:
- Don't check for i915 gen
- Skip test if Content Protection property is absent
