Move the panel DT node under `aux-bus` node, so it won't use the buggy
`ps8640_bridge_get_edid` to get the display modes. Also, change the
compatible string from "lg,lp120up1" to "edp-panel", so the panel-edp
driver gets the displays modes from the EDID instead of using the
predefined display mode (`lg_lp129qe_mode`) in the driver, which is
actually not working.
