I think it's entirely the same.  Instead of the I/O address space you
would use EC OperationRegions, instead of _Exx you would use _Qxx.

If we had an embedded controller device model perhaps it would make
sense to use it for all of PCI hotplug, CPU hotplug, memory hotplug.  We
don't, hence it makes sense to use I/O and GPE for all three of them.
