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
Changes in v3:
- s/igt_require_f/igt_assert_f/ (Ram)
- Clear property after test runs (Ram)
- s/drm_open_driver/drm_open_driver_master/ (Ram)
- Fix spelling mistake in log message
- Pull out property set/check into helper

Can you also hook up to chamelium to do CRC checks across a CP link?
