mainboard/asus/kfsn4-dre_k8: Fix broken dual CPU package support
The existing KFSN4-DRE support hung during ramstage while initializing
AP #3 if a second CPU package was installed. After analyzing the
Sun Ultra 40 M2 support code it became apparent that the K8 code
cannot function correctly if sequential RAM training is disabled,
and that there were a few other missing calls. This patch adds
the missing calls, adjust the CAR space to an appropriate level, and
explicitly defines the link numbers and connections in devicetree.cb
TEST: Booted ASUS KFSN4-DRE with 2x Opteron 8222 installed.
