AMD K8 fam10: Refactor Kconfig SB_HT_CHAIN_ON_BUS0
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.
