soc/amd/common/data_fabric/domain: write _BBN method in SSDT
Instead of having PCI0's _BBN method in the DSDT that always returns 0,
use acpigen_write_BBN to generate the _BBN method that returns the first
PCI bus number in the PCI domain/host bridge.
TEST=On mandolin the _BBN method in the _SB/PCI0 scope is now in the
SSDT instead of the DSDT, but still returns 0.
