AMD K8: Move SB_HT_CHAIN_ON_BUS0 default 0

Define the default value under northbridge. The list of boards this
patchset touches will change to use SB_HT_CHAIN_ON_BUS0 with
follow-up patch.

Based on code analysis, these boards already scan system bus
as the first (active) HT chain, so it is placed as bus 0
even when this option was not explicitly selected.
