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

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

Fixes: 88ec840270e6 ("arm64: dts: mt8183: Add dsi node")
Fixes: 19b6403f1e2a ("arm64: dts: mt8183: add mt8183 pumpkin board")
