[PATCH i-g-t v2 0/4] New rotation test

[Louis Chauvet]

The actual kms_rotation_crc test does not test all the rotation with all 
the formats. Create the test kms_rotation, which only test "full plane 
rotation", but for all the formats, plane and rotations configuration.

This new test allows to detect issues in [1], where the YUV rotation is 
faulty for reflect_x and reflect_y cases.
