Create new tests for checking if ILR (Intermediate Link Rate) is working
on eDP displays. Tests validate ILR from 2 perspectives:

* Physically check if driver can successfully train link by the ILRs 
reported from DPCD of eDP panel

* Check if driver does use ILRs as the link rate options while doing 
link training. And also validate that the train result is bandwidth 
sufficient for the required resolution.
