arm64: dts: mediatek: mt8183-kukui: Move DSI panel node to machine dtsis

Not all of the kukui machines have got a real DSI panel, infact,
some of those have got a DSI to eDP bridge instead: this means
that the address and size cells are necessary in the first case
but unnecessary in the latter.

Instead of adding a bunch of /delete-node/ which would impact on
human readability, move the entire panel node declaration to each
of the relevant Kukui machine dtsi: even though this introduces
some duplication, the advantages in readability surclass that.
