CI uses kernel config to force_probe. MTL is already being tested there.
Also there's no 'CI' or 'HAX' tag on this patch.
So I would assume this is the ask to remove the protection.
But based on this question from Andi and knowing that he is working on
the MTL w/a I'm assuming that this is not the right time yet to remove
this protection.

Please ensure all the diligence is taken before sending this patch again.

Also ensure that the current CI failures are fixed (gt_pm and gt_engines)
and that CI has a stable green picture.

Thanks,
Rodrigo.
