[PATCH 5/5] PCI/ACPI: Centralize pci_aer_available() checking

[Bjorn Helgaas]

From: Bjorn Helgaas <bhelgaas@xxxxxxxxxx>

Check pci_aer_available() in acpi_pci_root_create() when we're interpreting
_OSC results so host_bridge->native_aer becomes the single way to determine
whether we control AER capabilities.
