We currently apply _HPP settings only to:
- non-bridge devices, and
- PCI-to-PCI bridges
i.e., we do not apply them to PCI-to-ISA bridges and the like. It has been
that way since _HPP support was added by 40abb96c51bb ("pciehp: Fix
programming hotplug parameters"), but I don't think there's any reason to
exclude these other bridges.
Apply _HPP settings to hot-added PCI devices of any type.
