If SB_HT_CHAIN_ON_BUS0 is selected, HyperTransport chain for System Bus
is the first to scan and it will be assigned with bus number 0.
If HT_CHAIN_DISTRIBUTE is selected, each link will reserve a fixed range
of bus numbers instead of assigning consecutive numbers across all the links.
All fam10 have SB_HT_CHAIN_ON_BUS0 selected under northbridge.
Follow-up can easily drop this if we find this is dictated by architecture.
