[PATCH v2 7/7] arm64: dts: mediatek: mt8195-cherry-dojo: Describe M.2 M-key NVMe slot

[Chen-Yu Tsai]

The Dojo device has a M.2 M-key slot for an included NVMe on some
models.

Add a proper device tree description based on the new M.2 M-key binding.
Power for the slot is controlled by the embedded controller. As far as
the main SoC is concerned, it is always on.
