Subject: [PATCH] Revert "drm/panel-edp: Add auo_b116xa3_mode"

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.
