This reverts commit f25c7a006cd1c07254780e3406e45cee4842b933.
2p2c display configuration blows up dmesg when one connector is
disconnected, causing issues in CI.
Below are the sample errors thrown in logs:
[IGT] core_getversion: executing
[IGT] core_getversion: exiting, ret=0
Setting dangerous option reset - tainting kernel

Reverting the change for now to unblock CI execution.
