Where is this coming from? We have had common abstractions for
irqchips for a very long time. We can create fwnodes any odd way we
want, but why oh why should we invent another method for that?

We already have multiple architectures such as arm64 and loongarch
already having both DT and ACPI. Do they need another level of
"abstraction"? No. Why is risc-v so special?
