Pull PCI fix from Bjorn Helgaas:
 "Here's another fix for v4.5.  It fixes an ARM regression in v4.0 that
  causes many boxes to crash on boot, including cns3xxx, dove,
  footbridge, iopl13xx, ip32x, iop33x, ixp4xx, ks8695, mv78xx0, orion5x,
  pxa, sa1100, etc.

  The change is in code that's only built for ARM and ARM64.

  Summary:

  Enumeration:
    Allow generic PCI domains without bridge "parent" pointer (Krzysztof Hałasa)"
