arm64: dts: mediatek: mt8183-kukui: Disable DPI display interface

[ Upstream commit 377548f05bd0905db52a1d50e5b328b9b4eb049d ]

Commit 009d855a26 ("arm64: dts: mt8183: add dpi node to mt8183") adds
a device-tree node for the DPI display interface that feeds the external
display pipeline, to enable HDMI support on the Pumpkin board.

However, the external display is not fully described on Chrome devices,
blocked by further work on DP / USB-C muxing graph bindings. This
incomplete description currently breaks internal display at least on the
Cozmo board. The same issue was found and fixed on MT8186 devices with
commit 3079fb09dd ("arm64: dts: mediatek: mt8186-corsola: Disable DPI
display interface"), but the MT8183 change wasn't merged until then.

Disable the external display interface for the Kukui device family until
the necessary work is done, like in the MT8186 Corsola case.
