soc/amd/common/data_fabric/domain: write _SEG method in SSDT

As a preparation for the multi PCI segment group support, use
acpigen_write_BBN to generate the _SEG method that returns the segment
group number of the PCI root. Until the multi PCI segment group support
is enabled in coreboot, it will always return 0.
