Doing this in the buses is definitely wrong, as you say it's not bus
specific. I do however think we can usefully do this stuff in a SoC
specific place like a power domain, keeping the SoC integration code
together and out of the drivers. IME the SoCs where you need to do
different things for different IPs shoudl mostly still get some reuse
out of such an approach.
