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

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.
