If nothing else we'd have to resolve all the device probe ordering
issues (Grant's patches seem a bit stalled) and convert all the systems
using the API to handle deferring probes until their clocks appear.
Using an early initcall of some kind would help with that but it does
seem like a lot of trouble and I'd expect it'll end up getting forced in
on most systems anyway.
