Merge branch 'pci/enumeration'

- Clear bridge Secondary Status errors after enumeration since enumeration
  causes many errors (Vidya Sagar)

- Wait for Link Training==0 before starting Link retrain to avoid a race;
  this was done previously but broken by a faulty merge (Ilpo Järvinen)

- Rename PCI_IRQ_LEGACY to PCI_IRQ_INTX to be more specific about what
  "LEGACY" means (Damien Le Moal)

- Update return types of pci_find_capability() stubs to match the extern
  declarations for the actual implementations (Bjorn Helgaas)

- Drop unnecessary pci_enable_device_io() from pata_cs5520 (Heiner
  Kallweit)

- Drop unused pci_enable_device_io() (Heiner Kallweit)

- On 2016 and newer BIOSes, skip early E820 check for ECAM regions
  described in ACPI MCFG; there's no spec requirement for E820
  reservations, and some machines don't provide them (Bjorn Helgaas)

- If devices were disconnected while suspended, don't wait for them when
  resuming (Ilpo Järvinen)

 A convenient short-hand (PCI_IRQ_ALL_TYPES) is also available to ask for

 pci_alloc_irq_vectors() will spread the interrupts around the available CPUs.
