Whilst ACPI SRAT Generic Initiator Afinity Structures are able to refer to
both PCI and ACPI Device Handles, the QEMU implementation only implements
the PCI Device Handle case.  For now move the code into the existing
hw/acpi/pci.c file and header.  If support for ACPI Device Handles is
added in the future, perhaps this will be moved again.

Also push the struct AcpiGenericInitiator down into the c file as not
used outside pci.c.

why object_interfaces.h  and type name is in header,
at this point I don't see it used elsewhere beside the single C file.
If they must be exported, than mention in commit message where it will
be used.

is this necessary? 
it seems to be compiling just fine without it.

The error_fatal extern is in there.

I guess there is a non obvious path via which that's getting included
anyway. is in there and it's not obvious how it is included I'd rather
keep it as an explicit include to reduce fragility if the chain of
includes involved gets changed.
