[PATCH v14 1/4] PCI: Assume control of portdrv-related features only when portdrv enabled

[Kuppuswamy Sathyanarayanan <sathyanarayanan.kuppuswamy@linux.intel.com>]

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 of LTR and SHPC hotplug does not depend on portdrv, so keep
defaulting those to native regardless.
