Support for Rock 5 ITX

[felix-ebbe]

Hy,
I was wondering if there will be support for the radxa 5 itx board.

I tried to get it to work myself, but I do not understand how u-boot, device tree and so on, works well enough to get it running.
I did found this repo that has a .dtb file for radxa 5 itx but I was not able to include it into my yocto build.

Building an image for the rock 5b and booting it on the rock 5 itx does work, but not all the hardware is working (which is not surprising as the rock 5b does not have all the hardware the itx board has).
