I think it's just a side effect of the new RISCV arch being developed
outside of the mainline kernel. And they may have had a gpio driver
outside of the mainline as well.

Normally we don't encourage out-of-tree development, but new archs
are a bit of an exception since they have to be merged as a big
piece of upfront code at some point...

Anyways, if they don't have any GPIO in their machine yet, let's
let the RISCV maintainers apply this.
