Please be more specific. I agree we need a good reason for not just
using deferred probing, and PCI host bridges in general are no longer
something that needs to be probed early.

If you have a particular use case in mind that can't be solved in a
better way, we can talk about making this an earlier initcall (probably
not arch_initcall), but in general we try hard to avoid new ones
like this.
