These can be uint32_t to match drmModeConnector connector_id

We should have pipe < IGT_MAX_PIPES -1 as we are checking pipe+1 in the 
loop.

these can be one if condition instead of nested if:

if (data->display.pipes[pipe].enabled &&
     data->display.pipes[pipe+1].enabled)

I dont think we need this last_pipe.

I am wondering if we just store the igt_outputs instead of storing id 
and then looping to match the id with connected outputs.

It would be good to describe about the two subtests.

I think we need this for invalid case, describing new subtests.
