[PATCH v1 3/3] arm64: dts: mediatek: Add device tree for MT8365-based Pumpkin i350

[Laurent Pinchart <laurent.pinchart@ideasonboard.com>]

Add a minimal device tree for the Genio i350 Pumpkin development board,
which is based on a MediaTek MT8365.

The device tree is based on an initial version by Fabien Parent Based
written against the MediaTek BSP kernel ([1]). It has been cleaned up,
some features have been added (GPIO LEDs, ethernet), and some features
removed (audio, camera, display and dual-role USB). Those features will
be added back once the corresponding DT bindings and/or drivers become
available in the upstream kernel.
