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.
