This is expected if you still haven't implemented `.acpi_name` for
your northbridge device. In case you haven't tried it yet: Just copy
what `nb/amd/pi/00730F01/northbridge.c` does about `.acpi_name` to
`nb/amd/pi/00660F01/northbridge.c`.

Again, if the domain device doesn't implement `.acpi_name`, its parent
device will be asked. And in this case the parent, the root device,
always returns `\_SB`.
