This test actually *fails* in GLK and possibly SKL and others too. When
using limited range, the pipe crc when using the cursor plane is
different than the one when using an overlay plane, although the fb and
plane position is the same.
Since this test fails it should probably not be merged, but it is here
to prove the point of the previous patch.
