From: Kuppuswamy Sathyanarayanan <sathyanarayanan.kuppuswamy@xxxxxxxxxxxxxxx> Native control of PME, AER, DPC, and PCIe hotplug depends on the portdrv, so default to native handling of them only when CONFIG_PCIEPORTBUS is enabled. Native control LTR and SHPC hotplug does not depend on portdrv, so we can always take control of them unless some platform interface, e.g., _OSC, tells us otherwise.
