tests: kms: Implement CRTC stealing test
This test program sets a mode and framebuffer on a connector and cycles through all CRTCs, moving the connector to each of them in turn. This is useful to verify that CRTC stealing is properly handled in the DRM core and drivers. Signed-off-by: Thierry Reding <treding@nvidia.com>
