Add DTSI for Variscite VAR-SOM-MX93 System on Module and DTS for Variscite
VAR-SOM-MX93 on Symphony evaluation board.

This version comes with:
- NXP i.MX 93 Dual, 1.7GHz, Cortex-A55 + Cortex-M33
- 2 GB of RAM
- 16GB eMMC
- 802.11ax/ac/a/b/g/n WiFi with 5.3 Bluetooth
- CAN bus
- Audio codec

Please use a node name, which describe the hardware in general like "led".

The label property is deprecated, please use function and color instead:

You made significant changes, which invalidates both reviews. What's
more, you did not test the changes after adding them.

You must drop the tags after introducing such changes.

This wasn't here during my review

It does not look like you tested the DTS against bindings. Please run
`make dtbs_check W=1` (see
Documentation/devicetree/bindings/writing-schema.rst or
https://www.linaro.org/blog/tips-and-tricks-for-validating-devicetree-sources-with-the-devicetree-schema/
for instructions).
