I'm not aware of a way to do that, but I'm by no means an expert with
json schema. Krzysztof or Rob may know of a way.

I presume your rationale is any newly added platform would get a DTC
warning if they didn't add the samsung,uart-fifosize property?

Krzysztof and Rob also had concerns in the previous series about ABI
breakage on existing platforms, which is why this was only made
required for google,gs101-uart.
