drm/amd/display: Add connector to the state if DSC debugfs is set 



[why]
We want to trigger atomic check on connector, which DSC debugfs
properties have changed.

[how]
Add a helper function that iterates through all active connectors
and add them to the state if DSC debugfs parameters have changed.
