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.

Changes compared to the BSP version:

- Add ethernet controller
- Add GPIO LEDs
- Add reserved memory region for BL31
- Update board model and compatible
- Rename enable-sdio-wakeup to wakeup-source
- Drop audio support
- Drop display support
- Drop dual role USB support
- Don't use underscores in node names
- Normalize pinmux node names
- Remove unneeded labels
- Drop unneeded always-on
- Drop unused pinmux nodes
- Drop camera GPIO hog
- Update copyright
- Fix formatting
- Sort alphabetically

Are mmc aliases needed ?

Property order:
- clock
- pinctrl
- status

Actually, status should be at the end.
Apply this for the other nodes please.

That's how it should be ordered:
     bus-width = <8>;
     max-frequency = <200000000>;

     cap-mmc-highspeed;
     cap-mmc-hw-reset;
     hs400-ds-delay = <0x12012>;
     mmc-hs200-1_8v;
     mmc-hs400-1_8v;
     no-sd;
     no-sdio;
     non-removable;

     vmmc-supply = ...
     vqmmc-supply = ...

     pinctrl-0 ...
     pinctrl-1 ...
     pinctrl-names ...

     status = "okay";

Apply this for other node please.

Order:

#size-cells = <0>;

vusb33-supply = <&mt6357_vusb33_reg>;

Likely not. For mmc2, I don't think so. For mmc0 and mmc1, aliases
provide a fixed ordering that helps differentiating between the eMMC and
the external SD card. I don't mind dropping them if that's preferred.

OK, I'll reorder properties. Is there a document that clearly states the
preferred order ?
