Log:
  Announce PCI Segment Groups supported to PCI host _OSC.
  
  According to ACPI 6.3 specification:
      The OS sets this bit to 1 if it supports PCI Segment Groups as defined
      by the _SEG object, and access to the configuration space of devices
      in PCI Segment Groups as described by this specification.  Otherwise,
      the OS sets this bit to 0.
  
  As far as I see we support both of those as PCI domains for quite a while.
