Allow for per-device subsystem IDs
|Reported by:||uwe||Owned by:||somebody|

Currently both v2 and v3 only allow us to use one global set of PCI subsystem IDs, which is too simplistic. In theory (and often in practice) each PCI device has (or can have) its own subsystem ID.
We should fix this, at least in v3, possibly also in v2.
