These patches clean up and unify the PCI slot configuration across
the acpiphp, pciehp, and shpchp drivers. When these drivers detect
a newly-added device, they configure the bus. On ACPI systems, this
uses PCI bus settings from _HPP or _HPX methods.
Previously, each driver handled this separately with similar but not
quite identical code. This series adds a single pci_configure_slot()
function and changes each driver to use it.
Changes from initial post to v2:
- use static inline empty function rather than #define for non-ACPI (Eike)
- export pci_configure_slot()
- add comment about why we don't program default PCI settings for PCIe
- tidy up PCIe setting check for PCIe device
- move pci_configure_slot() and related functions to acpi_pcihp.c (Kenji)
- make acpi_get_hp_params() static
