arm64: dts: mediatek: mt8183-kukui-jacuzzi: Simplify DSI endpoint replacement

Currently the Jacuzzi dtsi file redeclares the full DSI endpoint tree
from the DSI controller just to replace the remote endpoint. This is
not necessary since the local endpoint already has a label that can be
referenced. This will also confusion when the inherited layout is
changed.

Replace the redeclared DSI endpoint tree with a label reference.
