For now? We also have software nodes and maybe we come up with something
else in the future...

I think we should use firmware-agnostic APIs as much as possible, and
only use OF- or ACPI-specific ones when there is no generic equivalent.
This makes the code most flexible.

Anyway, I am not proposing to change all of the regulator code, just
clean up driver core APIs.

Thanks.
