Merge branch 'pci/enumeration'
- Consolidate _HPP & _HPX code in pci-acpi.h and remove unnecessary
struct hotplug_program_ops (Krzysztof Wilczynski)
- Fixup PCIe device types to remove the need for dev->has_secondary_link
(Mika Westerberg)

PCI: Get rid of dev->has_secondary_link flag
PCI: Make pcie_downstream_port() available outside of access.c
PCI/ACPI: Remove unnecessary struct hotplug_program_ops
PCI/ACPI: Move _HPP & _HPX functions to pci-acpi.c
PCI/ACPI: Rename _HPX structs from hpp_* to hpx_*
