Merge tag 'pci-v3.17-fixes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci

Pull PCI fixes from Bjorn Helgaas:
 "These fix:

   - Boot video device detection on dual-GPU Apple systems
   - Hotplug fiascos on VGA switcheroo with radeon & nouveau drivers
   - Boot hang on Freescale i.MX6 systems
   - Excessive "no hotplug settings from platform" warnings

  In particular:

  Enumeration
    - Don't default exclusively to first video device (Bruno Prémont)

  PCI device hotplug
    - Remove "no hotplug settings from platform" warning (Bjorn Helgaas)
    - Add pci_ignore_hotplug() for VGA switcheroo (Bjorn Helgaas)

  Freescale i.MX6
    - Put LTSSM in "Detect" state before disabling (Lucas Stach)"
