mainboard: Add initial K8-compatible version of the KFSN4-DRE
This is a clone of the original Family 10h-compatible ASUS
KFSN4-DRE board, modified for basic K8 support to allow for
future K8 Socket F Opteron testing.
TEST: Booted KFSN4-DRE with 1 Opteron 8222 processor
KNOWN ISSUES:
* Second CPU package fails to initialize AP
This prevents use of a secondary CPU package
* Second memory channel of at least CPU package #0
does not function (crash at CAR handoff)
