Subject: [PATCH] Reland "FROMLIST: arm64: dts: mt8173: Fix elm panel DT node"

This is a reland of commit f6d05ad6348899298d49ca9e9602fffcdb98fec7

Original change's description:
> FROMLIST: arm64: dts: mt8173: Fix elm panel DT node
>
> 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.
