tests: kms: Implement universal planes test
This small program allows universal planes to be tested. Currently this isn't very flexible because it allows only the first plane of a given type to be tested on the first CRTC. However it should be simple to extend this with some additional command-line arguments. Signed-off-by: Thierry Reding <treding@nvidia.com> Reviewed-by: Emil Velikov <emil.l.velikov@gmail.com>
