[PATCH i-g-t] tests/intel/kms_joiner: Add a new test to validate non-joiner mode

[Karthik B S]

Hi Jeevan,

There is no specific debugfs entry at a pipe level to confirm joiner is 
enabled, but I found an entry in display info which shows joiner is 
enabled. "Linked to <> pipes as a (master|slave)". We should be able to 
parse this from display_info to confirm if joiner is enabled for a 
particular mode.

Thanks,
Karthik.B.S

Is there any debugfs entry where we get to know joiner is enabled or not. 2. Is it possible to get pipe active status after modeset/commit. Based on this we can validate.
