arm64: dts: mediatek: mt8183: Add missing endpoint IDs to display graph

commit be0b304eeb8c5f77e4f98f64e58729d879195f2f upstream.

The endpoint IDs in the display graph are expected to match the
associated display path number, i.e. all endpoints connected to
mmsys_ep_main must have reg = <0> and all endpoints connected to
mmsys_ep_ext must have reg = <1>.

Add the missing ID to all endpoints in the display graph, based on
mt8365.dtsi as an existing example that does this correctly.
