[PATCH v5 5/8] hwmon: (k10temp) Stop matching Hygon devices

[Lin Wang]

k10temp matches the Hygon F3 device and uses the AMD SMN accessors.
These accessors derive an SMN node number by subtracting PCI slot 0x18
from the F3 slot, then pass the result to amd_smn_read(). Hygon PCI
slots do not encode DF node identity, and their SMN roots are grouped
by socket.

The derived node number therefore has no defined relationship to the
Hygon DF node or its SMN root.

Remove the Hygon PCI match and Family 0x18 branch. Hygon temperature
monitoring requires the Hygon node and SMN interfaces and will be added
separately.
