[PATCH] Revert "arm64: dts: mediatek: mt8173-elm: Move display to ps8640 auxiliary bus"

[Pin-yen Lin]

This reverts commit c2d94f72140a28d0f516b7c5e8274a9c185a04ff.

The `lg_lp120up1_mode` defined in panel-edp.c is not working for some
panels used on elm/hana devices. Move the panel node out of the aux-bus
subnode so the driver only uses the modes retrieved from the EDID.
