agesa/family16kb/northbridge: report acpi namespace
Add a function domain_acpi_name to return "PCI0", rather than
falling back to the parent' device's "\_SB" label. This repair is
required for the LPC TPM device to register its presence without
blowing up the table and preventing the payload from finding SATA.
Before change, the TPM device reported as:
\_SB.\_SB.LPC0.TPM
After change, the TPM device reports as:
\_SB.PCI0.LPC0.TPM
A separate change submission will correct "LPC0" as well.
