  This reverts commit 70e0d5550f5cec301ad116703b840a539fe985dc.

The overridden mode fixes the panel glitching issue on mt8186 chromebook.
However, it causes the internal display not working on mt8173 chromebook.
Revert the overridden mode for now to let mt8173 have a functional display.

Given that the breakage for affected mt8173 Chromebooks is pretty bad
(black screen), I'll plan to just wait an extra day for any screams
and then I'll apply to drm-misc-fixes.

It caused a merge conflict against drm-misc-fixes since other panels
have been added in the meantime. I'm going to stick this in
drm-misc-next to avoid the merge headache. If someone is affected and
really wants this in fixes, please shout and we can figure out how to
make it happen.
