Subject: [PATCH 1/2] arm64: dts: mediatek: mt8183: Disable DPI display output by default

This reverts commit 377548f05bd0905db52a1d50e5b328b9b4eb049d.

Most SoC dtsi files have the display output interfaces disabled by
default, and only enabled on boards that utilize them. The MT8183
has it backwards: the display outputs are left enabled by default,
and only disabled at the board level.

Reverse the situation for the DPI output so that it follows the
normal scheme. For ease of backporting the DSI output is handled
in a separate patch.

Fixes: 009d855a26fd ("arm64: dts: mt8183: add dpi node to mt8183")
Fixes: 377548f05bd0 ("arm64: dts: mediatek: mt8183-kukui: Disable DPI display interface")
