I'm done reviewing this because I'm tired of repeating myself and you're
just throwing crap at the wall and seeing what sticks. Get someone else
working on QCom stuff to review because I'm done until someone I know
and trust reviews it.

Once again, what's the difference between dsi-controller-sc7180.yaml and
dsi-controller-sdm845.yaml? I don't see one. If there's not a
difference, why do we have msm/dsi-common-controller.yaml? If there is a
difference dsi-controller-sc7180.yaml and dsi-controller-sdm845.yaml
should *only* have what's different because
msm/dsi-common-controller.yaml should have everything that is the same.
