What exactly do you want to reuse?

It looks like that's just several lines of code in acpi_pci_wakeup()
and acpi_pci_propagate_wakeup() which invoke ACPI-specific lower-level
functions, so IMO not worth it at all.

The structure for other platform code may be the same or similar, but
the details will almost certainly be different and I don't think that
having more callback pointers in pci_platform_pm_ops is necessarily better.

Why are they needed?
