Announce PCI Segment Groups supported to PCI host _OSC.

Browse Source 
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.
