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.

This commit was sent to fix display functionality on MT8173-Elm (Acer Chromebook
R13).... apparently this should get fixed with [1].
Investigating if this is the case.
Regards,
Angelo
