Added negative test to verify the different scenarios for big joiner.
In the test, modeset is done on Pipe A for a big joiner mode and
a second modeset is attempted on Pipe B which is expected to fail.
Same functionality is validated for other pipes as well.

Secondly, the reverse is tested where a modeset is done on Pipe B
and then a second big joiner modeset is attempted on Pipe A which is
expected to fail. Same functionality is validated for other pipes as well.
